Ideally, something more than that. My mission, for example, has 2 klingon houses fighting each other and is a Klingon only mission. So it needs Klingon on Klingon on player violence. So I'd really like somewhat greater control.
And, of course, the ability to change aggro on the fly, so we can set up situations like Rescue Deferi Captives daily, where something goes from neutral/friendly to hostile.
