Can someone explain to me why there is PvP gear in the game? Did Blizzard make a statement about this at some point?
I mean, surely it's no problem coming up with gear that satisfies both applications. If defense stats on PvE gear are too low for player-vs.-player battle, why not have resilience on PvE gear as an added attribute?
So it looks like there's another reason for doing this. As I understand, it's a source of much complaint.

Personally, I find it a bit annoying in world PvP. For example, I don't want to carry an equally powerful PvP set around all the time that I can switch to whenever there's an attack on Stormwind.
