I'm sorry Johan Osterman. I was pretty unclear in my Last post. The curse of jumping into a thread without reading all the Posts previous first.
The units that have battlefield summons where the ones that I felt would benefit from a "weapon unit", like the Titans Owl. The unit is so closely linked to its summoned ally that one could argue that if one fall then both go. The Moloch could have a small group of imps circling him in his graphics and be granted a "Imp horde" weapon.
The dominion related summons are the ones I felt could benefit from a "summon ally" ability. It's not what you intended perhaps as there's a difference between a passive and active gain of a free unit.
A silly idea might be an Allies Available counter ticking that lets you summon more than one unit at the time, up to dominion score, as long as there is units available on that counter. It becomes a choice of expanding fast in early game or having "instant horde" in the late game. But by now I'm sure you guys are sick of wishes, demands and whines for extra options.
I reckon it's a lot like journalism. As long as one churns out somewhat rewritten newstelegrams noone gives a rats *** even if you misspelled everyones names, where it happened or if it was three days ago. But write one good article and people complain like there's no tomorrow. Everyone wants a peice of a masterpiece so to speak.
