Ok, I know there have been a few dmg exploits that people have found concerning warlocks and paladins and hunters. Im going to go into detail on how to do these exploits.
What is Needed:
1 Affliction Warlock (with Curse of Idiocy)<many servers dont have CoI, but you CAN get it from a GM. All you have to do is ask. Be knowlegeable about the spell tho, otherwise, the GMs think you are yanking their chain...its a little known spell. >
1 Protection Paladin (with Blessing of Kings)
1 Your choice of Paladin, druid, priest, hunter, or mage
Now, to get started:
Spec your Pally Holy for Holy Guidance
Spec your Druid Ballence for Lunar Guidance
Spec your Priest Holy for Spiritual Guidance
Spec your Hunter Marksmanship for Careful Aim
Spec your Mage Arcane for Mind Mastery
Ok, once your are specced correctly, have a paladin cast Blessing of Kings or Greater blessing of Kings on you and then duel the warlock. The warlock has to be full Affliction specced so as to have many many DoTs. (side note: have the Lock remove all his gear or he may kill you because of his spell dmg bonus)
The warlock needs to throw on Syphon Life, Corruption, Unstable Afflction and any others that he has and then finally he casts Curse of Idiocy. Once Curse of Idiocy has stacked 17 times, you intelect and spirit shoot through the roof into the 100s of millions. Because of the tallent specs that you have done, your spell dmg is based on the spirit or intellect that is now shot through the roof. There is no rez sickness required for this and no Corruption sword required either. As long as you spec how I have linked, you will have ubber dmg and can 1shot anything in the game. (I have found that mages and hunters are most efficient for clearing because of multi-shot and the mages AoEs. Now go kill stuff, and if you get banned, dont blame me...I just got full account banned from my server last night because of this...so SERIOUSLY, dont get caught.
