Alright, then say that instead of the ignorant sounding post you made before. And then tell me how practical it is to have more than one balance team in a single game.
It is called pararrelization of the work and it works in any kind of task that can be divided in simplier ones.
It is not only about balance, but also about features. Balance is game wide, PvP features are related only to PvP and we’ve seen only a couple added in one year.
