So in other words, Larian needs to create the perfect AI ;-) Get on that ForkTong!
I haven't played the alpha, is there much of a problem with NPCs stupidly walking into ongoing spell-effects and hazards? I can understand the desire for an option to turn off friendly-fire if that is the case, even if I would much prefer to just live with the occasional NPC facepalm moment. Besides, there's always save & reload.
