Just a suggestion here but I LOVED D:OS and also always opt for necro's smile.

That being said summons were way OP in the first game. Someone said that Larian said SM would allow two summons...if they are as strong as before that'd make sense.

I have a suggestion to help that.

Maybe instead of using mana the SM could use his HP to summon however many units he can afford HP wise. Maybe he pays a % of the units HP and doesn't get that back until the fight / encounter is over.

Alternatively / additionally could have the summons linked to his HP so that if they die or take dmg he takes dmg. I don't particuarly love this idea but I think this could be a cool feature. Super stoked to see what Larian does with this.
