I've been a bit out of the loop and i don't know if it's been asked already, but is there any chance of making a customizable AI on your mercenary so you can choose if you want him to fight or to just stay out of fight
(buff merc AI) and also one that groups your merc to you so he can receive your buffs without him drifting off.

Also regarding the act2 mercenary taking obnoxious amount of time to activate his aura, is it possible to fix that?
