Hey i guess you all seen Doomcasters video? about the spot in Icecrown where you can nuke those skeletons with 1min respawn?
Well this is the way for a hunter no videos or pictures sadly but here goes!
First i will recommend a spec like this: Talent Calculator - World of Warcraft
You can **** abit around with the spec yourself
Anyway a Gorilla ofcourse! You just need a gorilla simple.
Main tactic: Pull them with mount, when you have them gathered. Get the monkey to thunderslap them so it have the aggro, mend pet, Explosive trap, Volley.
Its it bit hard to get the technique running in start but you manage.
(Gorilla spec i prefer Pet Calculator - Wowhead)
