I don't want to micromanage the party on my first run so the companion AI - as a necessity - must be smart enough to follow tactics, especially with barriers, regen potions, and health potions, and not ignore them half of the time.
And eight potions for the party sounds like a mistake. If you have it set in your tactics that companions use a potion when, for example, their down to one-fourth of their health bar, and we run into a trap or get overwhelmed by the next group of enemies or something, and they all suck down a health potion again, then you're screwed for the next few fights.
And what if I can't even leave a dungeon midway through it to go back to camp and refill my potion belt? Its been the case in some instances in the past games that once you enter a level, you cannot return to party base until its completed.
i really hope that the lack of healing isn't a problem, but I can certainly see it being one for me.
And when it comes to the lore, mages that are healers are the most sought after, especially during war. My mage can't learn a basic heal spell for herself when she would need it most? And no other mage in the party - an imperial enchanter, a top class tevinter mage, and a self taught fade expert - can either?
