Got it, playing it.

There are a lot of innovations in this game but the party AI is just killing me. It's never been very good but Storm seems to have really mangled it. When a battle finishes, my whole party starts running around in circles looking for a target. They initiate combat without being told to do so and, worst of all, my fighter refuses to use his sword for long. He'll switch to whatever weapon I've picked up - putting his shield away if it happens to be two handed. ARGH!!!

Maybe I'm just picking some bad AI options? I have most of them off, looks like I'll have to turn them all off again. <sigh>
