If you don't want to play a hybrid- don't. But the Devs shouldn't punish those of us whom enjoy hybrid characters either in their creation of the Job system, and believe it or not, the Job system is probably any FF's ultimate tool to cater to BOTH sides of this argument.

Part of building this game FOR XI players IS to fix what was wrong with XI from the very begining... making hybrid building not only possible and effective, but FUN.
