A class you can constantly mess up on and everyones fine with it? A dps is the easiest to get away with this, but no matter who you pick if someone is looking for faults in others theyll find them. DPS parsers let others know how everyone is doing, and are allowed by square as long as you dont rub it in other peoples faces.

What im trying to say is, play what you want. I had a friend go from pugulist/monk to black mage since they werent having much fun 60-70. This was after them playing monk all of 1-60. I play mostly warrior, but ive been playing summoner cause theyre also fun. Play what you want when you want.
