Run 40% Extra Speed, Shaman
This is really fun, but makes it look like you're speedhacking.

The way it works is you've got to drink a noggen elixir to turn into a skeleton, then cast ghost wolf. You'll stay in skeleton form, but run at 40% extra run speed.

Fun fun.

Perma Inferno Attack on Jadefire Exploit

So rumors of a certain bug involving Jadefire Tricksters in Felwood and permanent enslavement abound.

I decided to check it out myself. A lot of people are trying to keep this on the downlow, which I think is stupid. It's an obvious bug, and needs fixing.

Anyways, here's the skinny, and I'll tell you why I am posting this:

Basically, I've been able to repeatedly keep a permanent Infernal by summoning it, and sending it to attack a Jadefire Trickster. The Trickster will focus attention on your pet, but occasionally will cast Curse of Tongues or Cause Insanity (mind control) on you.

Once you've been tagged with Cause Insanity, your Enslavement debuff will wear off your pet, and the pet will be permanent.

Wah wah, shhhh, don't tell anyone, whatever. The reason I report this bug is bigger than just having a permanently enslaved pet.

I took a wind rider with the Infernal.
Literally.
As soon as I began flying, the pet bar did not disappear, nor did the pet health bar…they just greyed out as if I were mounted. When I arrived at my destination (Marshal's Refuge) the Infernal popped up a second later, ready to rumble. Then I flew to Ratchet. Same thing. This wasn't some fluke either, I can reproduce it any time I want.
Anyways, the whole reason I bring this up is because it can obviously be done, so why can't we have our regular pets follow on the Wind Rider?

Blizzard, refunding a shard for taking the Wind Rider is a step in the right direction, but when all is said and done, we STILL have to re-cast the pet and regen the mana when we land, a process that takes much longer than replacing the shard.
I also play a 60 Hunter. When I get off the Wind Rider, I whistle, and a second later my pet appears, ready for action.
So again, my question. Why can't warlock pets follow on the Wind Rider?

And while I'm at it, why on earth does Demon Armor cost 3x as much as other self-buffs? What does that extra cost balance against a spell like, for instance, Frost Armor?

And finally, please fix the Enslavement bug.

I made a video, it can be downloaded here: http://files.filefront.com/enslavementavi/;5340906;;/fileinfo.html

OK, now that more information has come to light, I'm gonna add a quick step-by-step process here:

1. Enslave an NPC demon or summon an Infernal/Doomguard.
2. Attack a Jadefire Trickster, until you get mind controlled (Cause Insanity) and you're forced to attack your own pet. Alternatively you can duel a priest, have them Mind Control you, and make you attack your own enslaved pet. I don't know if it's the act of attacking your own pet while you're Mind Controlled that causes this, but it's been the case every time I've done it.
3. Wait ~4 more minutes for Enslavement debuff to fall off.
4. If you want to forsake your new enslaved pet's own abilities, you can log out, making sure your new perma-enslaved pet is on Defensive, and you're in a safe place where he won't get attacked or pick up aggro. If the pet is set to Passive, your perma-pet won't do anything after you log back in. This works great with an Infernal, since Blizzard didn't see fit give them any abilities.
5. Log back in, and you can summon/enslave a new pet.
6. Take a Wind Rider, and your enslaved pet will come with you. Often (haven't confirmed always) you will instantly warp to your first destination. On subsequent flights, your demon seems to run invisibly below the Wind Rider (even causing aggro) until you arrive at your destination, where it will stroll up to meet you, ready for more action.

The gist of it is that if you're mind controlled by anything at the moment when enslavement of a demon (or infernal) would normally end, supposedly it is yours until you zone.


Respawning Scarab Coffers
If your in an aq20 group and your group downs at least the second boss then all the mobs up to him do not respawn after a soft reset, aka 30 minutes. But, the scarab coffers do respawn along with the level 55 non-elite scarabs. So spam around and buy as many Scarab Coffer Keys as you can and then when you go on your aq20 run stay after the run is called and after 30 minutes of no one being inside the instance the scarab coffers respawn. You take your key and take them all for yourself. Typically you get one idol and 11-15 scarabs.

Hunter, Drop Freezing Trap in Combat
tested and verified this with my own 60 hunter, and my friend's. If you use this macro:
/script PetPassiveMode();
/cast Freezing Trap

You can successfully drop a trap while in combat. Testing this should only require 10-15 seconds as it is not "Maybe it will work" thing, it is extremely easy to pull off, just hit the macro three or four times in a row.


Edit:

Solo Naxxramas Mobs For Epics
Plague Wing

Pull is 2 slimes, 3 ghouls.
Pretty Much for Ranged fighters, but hunter is the best due to the 30 second Oh crap button. You are split up the 2 slimes and ghoul pulls to allow you to solo a slime. These slimes move incredibly slow and are super easy to kite. They have about 140k hp and take a long time to kill. You wait for gargoyle to path then tag one of the ghouls book it to the corner of the outcropping and jump on on the ledge, the jump is tricky but with a little practice its easily done. Wait for them to return and the slimes path so slow they get stuck part way and stay there. You check each ghoul to see if thye are still targeting you and if they are arent you drop down and the slime with follow you without the rest of the pack. Kite untill dead enjoy your scraps and 5% chance at an epic. I personaly have done over 80 kills and have no recieve an epic yet, i have 80 or so scraps and about 15 rune of thawing scrolls.

Here is a link to a mage video on how a mage can solo the whole pull.

Have fun! Who knows when and if they will fix it. It takes a very long time to kill these things but if you get a epic drop its totally worth it as some of the drops are better then BWL loots.

Princess Huhuran Exploit
Sheen of Zanza. The item from ZG that gives you a 3% chance to reflect spells. Well, on Huhuran currently it reflects the entire poison volley, all damage, everything, 100% of the time. This is 100% confirmed on the wow forums as well, guilds are using this all the time for an EZmode Huhuran. Blizz has said nothing or patched this in 4 weeks now.

Remove Enemy Stealth With Dummies
This one is short and sweet.
If you use any target dummy near a stealthed player, it will bring them out of stealth instantly.

Rogues Avoid Death on Wipes
For Rogues.
Everytime you go raiding in MC, BWL, Aq40, or Naxx, and you wipe and tried to vanish but it will just put you back in combat and unstealth you.
I noticed when you vanish it puts you out of combat for like 2 seconds. So i made a macro

/cast Vanish
/logout
/logout
/logout
/logout
4 /logout so incase it could't do the first one

You will have to wait 20 seconds and you will logout and the rest of the raid will die, and log back on when its safe. This way, you wouldn't have a repair bill as high as others.
Or you get the Addon, Itemrack, that takes of all your gear for you. Vanish and use the addon.

Warlock Repair Exploit
Basically this is using hellfire to get out of dura loss.
When raid is about to wipe just lifetap down to low health and hellfire to death. This is prevent any dura loss.
Useful when learning instances such as naxx.

Attack a City Without Being Flagged
This trick allows you to mess with the opposite faction and annoy this, this is kind of known but some people dont understand it, I had to figure this out myself because people dont like to tell how they are doing it. (Doesnt work on real people)

Basicly what the trick is is to attack a city, without being flagged.

During this trick at any time, never flag, if you do it wrong you will flag, this only works with hunters. All you do is aggro a guard, or whatever your going to attack, never attack it at anypoint (im not sure if you can have pet on aggressive and just have him attack what he pleases or not, passive doesnt work) Make sure your pets on defensive. When the guard strikes you the pet will attack. Its best to have a few potions on you incase you pull 2, if you heal your pet you will probably aggro the second one, dont attack it though. (Yes you can heal your pet without PVP'ing)


Kill a Player in a Duel, Warlock
Found this out the other day dueling a lvl 60 mage,
(found as a warlock, not sure about other classes)
Heres how it works:

Simply duel the person you want to kill and just before you win the duel hit your imps Fireball, just as the duel finishes your imp casts his fire ball and kills the victim =)

Fight in Wisp Form, Test Servers
I was playing around on test servers and in alterac valley I died and became a wisp (Night elf racial) and then warsong queue came up and I joined before I could rez. Then I was an alive wisp. I could attack and use all my spells but I couldn't mount (no mounting while shapeshifted.)

Update: I was playing around and found another way to do it. Die in a battleground and while a wisp, /afk out of the game. You will retain your wispiness and 50% increased speed.

It's true, although I cannot yay, I have seen it work and heard people talk about it. You queue for WSG (this only works on test server BTW!!), die, wait for the WSG to pop and enter it, you will be ressurected upon entering it and a wisp! You stay a wisp even after you die and even after you live, the best part is that they have no attack animation so sometimes people freak out and don't know who is attacking them.

I remember a NE hunter was a wisp and I was on horde and I was thinking "Uhh, can I see other factions ghosts now?" It was pretty crazy.
