I'm somewhat unhappy with the NPCs reaction to friendly fire. As soon as you hit NPCs directly or with area effects, they turn hostile. This is quite annoying given that NPCs who join combat on the side of your team repeatedly run right into the fire fields or poisonous clouds your mage creates. If they suffer damage from crossing such fields, they react as if you had attacked them intentionally. I had a few fights where I had to reload and try again, sometimes even refraining from using area effects in combat to avoid making NPCs hostile.
