He is saying that the game will have you go to zones that will flag you for PVP. So no PVE servers, which will limit it to only players cool with that.

It is not pay to win, you are playing against yourself. And no one is affected by it. End of story.

Its not that really, I was thinking about this and it can come down to the end result. If the tank messes up its over. If the healer messes up its over. If a dps messes up you can recover. I know its not always the case, but its the fact that if you want to be in the position. And on the fun factor its hard to beat damage. I play them all, and its hands down the one I would do first.
