Hello,
As for point 1. I would say that is not super important to me, but would be nice thing,
For point 2. I would say that the only stipulation I think they would need is you have to exit combat before they resummon themselves. If they could resummon themselves during combat I think it might be a bit to overpowered since I could just sit one guy in the back on passive or retreat one when the other ones die to make sure one stays alive at all times and never have to spend a cooldown or end to get them back.
I would like to add one as well, the ability to have them go to auto passive when below lets say 15-20% health. It would be something I would like to toggle on or off, so I can have them fight to the death sometimes, but othertimes I can have them fight until they are about dead and auto go passive.
Oh hey as were thinking about this, Another one I would like is the ability to leash your pets to stay within certain range of you. Like lets say they were not allowed to leave Supremacy range. That way I can let them go ham but know they wouldn't run into the next group (depending on how close I am) or go without all the great buffs they get by being near me.
