BM hunters are extremely competitive at PvE on Live. We are trying to get Survival and Marks up to that point. It's harder to to talk abour PvP because we have made so many changes that the problems on Live may not be the same problems of LK. In short, we just need a lot more PvP testing. A lot.
Apparently BM is miles better in PvE than MM or SV. Apparently they are trying to balance it and haven't looked at PvP yet.
Best get cracking blizz.. 2 months to go.
