The concept of pvp stats may be fine, but their implementation is flawed. Resil does almost nothing, and pvp power has made healers damn near unkillable.
I agree, also, you should not need to pve to get gear for pvp. However, I'd be inclined to say that there is no more or less accessibility to someone wanting to break into the pvp scene as there was before pvp power and the like. And the game at current is very imbalanced, which is even more likely to turn away someone new to pvp after they get globaled a few times or sit through 10-15 seconds of CC every fight. This game is not new player friendly for pvp, and gear, at this point, does nothing to help that.
The thing is, if pvpers truly cared about balance, then they would be clamoring for NO gear for pvp, just throw everyone on the same playing field a la challenge modes. Rewards can be transmog sets, mounts, trade goods, what have you. Putting everyone on the same playing field would make it all about skill (or whos class is more OP, of course, but that's imbalance problems and this talk is about pvp gear). I can really only see backlash being from people who LIKE being ahead of people, not through skill, but through gear.
