The thing is I thought with the pve and pvp talents separated and how they are handling things was going to make balancing easier for them? I thought Blizz said this would make it easier to deal with pve side issues etc. The other thing I think they never really thought much about was if someone puts 30 levels into say into one spec and weapon and then decide they want to reroll to another spec and weapon, they are going to be gimped a bit until they get more AP.
I just always thought the main issue was its hard to balance pve when you always had to deal with pvp ramification and vice versa
