Pretty cool stuff. Mikizle is a hunter that I play with on Sargeras alliance, and he's taken the time to record some videos of what survival hunters can do right now in the beta.
I must say that the hunter changes have been nothing short of outstanding so far this expansion, and the class is shaping up to be a lot better than it has ever been before (and that includes pvp).
Check out some of his videos here.
Keep up the good work, Mikey!
