It's not that.
I'll give you an example:
Curst Prison was full of guards of the same type. I danced in and started fighting, trying to first soften them with spells such as Desert Hell and Ice&Fire. Well, when Dak finishes the spell, my poor fighters have run to the line of fire and the globes freeze their innards and scorch their bones. At the same time; all the guards use their clever tactic of massing over one character and whacking him till the end of time. Grace the idiot runs to heal the poor bugger and almost gets wasted in the process. I can't cast any spells because all my chracters are i midst of combat and on the other hand all the single-character-targeting spells are worthless. So, my brave party proceeds to do their thing; bash heads in till they reach the floor. And this continues till the freakin' Pillar of Skulls. Nothing but mindless hackin', which is sometimes paused by a flashy spell-effect, breaking the monotone somewhat. Mass destruction spells just lay unsused because each time you found enemies; they rushed you. Yes, I could have used a spotter for bombardments, back then I didn't acknowledge that. Still...
I love the game so much, but the combat just irritates me. Even the Trias fight consisted of me quickly standing aside when Dak and Grace used every scroll and spell and item on him. One long standing of cutscenes, you must watch every freakin' time.
Edit: Though Meteor Storm Bombardment was nifty.
