I hope Yoshi-P will not listen to all those immature requests.

All the nay sayers(im assuming) are having a problem grasping actually HOW this would happen WITHOUT affecting PvE or causing major issues with balance. The WoW recent approach was they kinda split certain abilities(like the CC ones) and lowered their duration and others having decreased effects. That however might be easier said than done in a PvE based game. Also because WoW system is a lot more restricting than our current and future Armory System. Their talent trees also are split because the PvPers choose the best PvP options and vice versa. If this could be explained you might be able to persuade them.

edit: I'm all for arena fights though. Open World PvP not so much(even though It can be fun).
