I am greatly enjoying the hunter changes, and I am having a lot more fun in PvP now. Aspect of the Fox makes kiting melee classes even easier now, and even some keyboard turning casters that can't keep up. Camouflage has helped me gain the upper hand quite a few times now, and Cobra Shot is great for keeping up Serpent Stings on those rogues that might try to Vanish on me. >=)
Overall, I am really enjoying my Hunter in PvP so far, besides some trouble from a few overpowered classes that are bound to be nerfed. How is everybody else doing, PvP-wise? I've yet to do Arena. How's that going?
