Did the game get too complicated, or am I just an idiot?

[Alahra]

The game did get more complicated just for the sake of it, but not really too complicated.

I'd say that probably varies somewhat from class to class. NIN didn't change much (though I think they have needless ability bloat), for instance, but other classes, such as BLM, have a lot more to worry about now that they didn't have to before.
