As anyone who's played FFXI could probably tell you, customization is a myth. Hell, even bonus stat allocation in this game is something that's largely unnecessary to have, because the majority of the classes really only have one worthwhile choice, which isn't really much of a choice at all.

What would end up happening (because this happens in *every* game that allows customization) is that the bean counters will find out what has the greatest overall practical/statistical benefit, and then everyone will have to run that particular setup or they will be gimp as hell. It's merely an illusion of choice.
