In reply to the "I play how I wanna play" users:
This game is very tuned towards specific roles doing specific things (rotations in most cases). There is no (or very minimal) "I play how I want to play" in this game. If you do paladin, you use shield oath and you use halone combo as your bread and butter. Black mage can do fire 3 -> fire 1s -> Blizzard 3 -> fire 3 loop. Nothing fancy and can certainly be improved..but it is enough to do your job.
Nobody will care if you flub a rotation, but if you are 50, you really need to sort out your role.
