Well, I raid Kara and Gruul ok. I just got my 3rd piece of Voidheart and Prince's dagger along with a bunch of other kara gears. But to be honest, raiding gear is not ideal for pvp due to mediocre stamina and the lack of resiliance imo. The problem with shaman is that it is extremely hard for me to control him plus he has a shit load of burst damage. So say if he pairs with another warlock, they just CC our pally, and dual dps me down while i am trying to get rid of tremor/grounding. yes, this maybe due to my skill, but that is why I want to seek help here.
I do use hs every fight. And running around the poles causes tons of trouble for my healer, since she does not have any reactive heal or HoT.
As for what else do i want to know, I am trying to understand other classes better and learn their strength as well as their weakness so that i may have a better chance to beat them.
PS: I really appreciate your input.
