Most fun class in the game Rift?

I hate warriors and already had a rogue so either a mage or cleric is what I'm looking at. I really like casting, but I also like healing. I enjoy to PvP more than raiding though, if that helps. I know clerics have more durability than mages, but mages can burn down anything. So yea, if anyone has any suggestions on which one is more FUN to play not BETTER, I would appreciate it.
