Haha...no.

Not too long ago there was a thread about what would be the absolute limit that would make people quit. There were a few things, but only 2 really stood out:
1. If Cash shop became obligatory
2. If PvP became important to PvE play.

I don't mind something like letting people buy tomes with PvP currency the way you can also buy them for Seals and the like, but 'requiring' any PvE player to play PvP would be an incredibly bad move.
