I just made a search on the forum and i didn't find anything as this idea so lemme expose it.
I played FF12 some time ago, i just remember this now and something there that i found very interessing were the gambits, in fact the gambits are a successful implement in Dragon Age 2 too, with the name of Tactics. Both vary in each game but the objective are the same, a semi-controled AI for the party members.
What are the Gambles/Tactics/ They're AI slots that each NPC has, so you can configure a single action.
Ally: Shar-Teel < or = 50% life, Action: Cure serious wounds spell.
Ally: Self < or = 50% life, Action: use minor healing potion.
Enemy: Hasted, Action: slow spell.
I really don't care much if this idea will have place on Baldur's Gate or no, i would use this if the implement come to be made, but i'm from the old school and i like to pause the game to take my decisions, however to make the game a little more versatile, this idea can come in hand.
On FF12 you had to buy the gambles to use them with skill points, the same in DA:O. But in Dragon Age 2 you gain a x number of gambits per level (and based on the class if i remember well to).
This can make some new customers with ppl that don't know baldur's gate and please some of the hardcore gamers here (making possible a no pause game if ppl use the AI well), but i will play the game with or without this implement.
