A quick post for my melee friends, on Kologarn and how to do AWESOME WTF DPS on him.
If you follow my simple guide and use your uber aoe attacks (whirlwind, sweeping strikes, DnD, consecrate, whatever rogues do...) you'll finally beat those mages on the DPS meters.
Kologarn has 3 targets, his body, his right arm and his left arm. His right arm will be your constant focus, when its up, but... the important thing to realize, is all 3 of his hit boxes are stacked up on one another, and if you stand right by the tank, and face his chest, you will be in range and able to see all 3 targets without moving. You can even stand right beneath his left arm and hit all 3 targets as well.
Poorly drawn diagram:
Hope this makes sense to everyone! I am not sure if Hunters can trapdance and drop their trap right under his chest... but it might be worth a try!
