I think this is something that bothered me most about the game. Bosses could only be defeated using select few stratagies. By that, I mean theres only 1 real way of dealing with them that will be the same as everyone else (until late game where 'death' and other cheap abilities become available).

I only realised this when I had to look up stratagies for some bosses. If I even attempted to use any other class of character than what was sugguested, I would lose. If I tried to do it my way, I would eventually die. You cannot get your characters any stronger than what the crystarium would allow for certain parts in the game, so you must rely on stratagy. I believe there is only a single strategy per boss.

Did anyone else find this?
