This was just a thought I had, but I think it'd be cool if you could force Gambit actions on allies with a script call, like you can change their aggressiveness or offensiveness.

It's just a thought/suggestion though. I think, if it can be done, it'd help pre-define some characters and make them fight with their own style. Either that or keep them from spamming skills that don't do anything other than calling a common event (I have a visor skill that reveals hidden enemies, and some other skills that make one actor switch his special weapons)
I use common events a lot, so such a feature would be really awesome for all the reasons stated above XD
