I can understand why people would want it for PvP servers, they get the world PvP that they think they didn't used to have. But people on PvE realms seem less than enamored by it and tend to be finding it quite a nuisance as per what I've been reading on the official forums.
Of course it's got a lot of problems that need to be ironed out, but should that be done only in the context of PvP servers and just put PvE servers back to normal?
