The second big problem I found is definitely with the combat system. I don't mind the boss fights, as most are done with only one character, although the boss patterns are too easy to follow, but the normal battles are a headache. Every time I spy a large open area I pray there isn't a battle there, since the ally AI is disgustingly bad. I can say with much certainty that any character you don't control will inevitably get the crap kicked out of them.
I also don't like the power balance. The melee characters can dish out pretty decent damage, but the ranged fighters barely scratch the enemies. So not only does it take an hour to kill a mediocre bad guy, but you also have the disadvantage of a narrow field of view, and no way to 180 and see what's behind you.
