That's exactly what I mean... I think the summoning ability shouldn't be necessary for resurrecting the dead... and instead of hives and crystals, it should be used to cast something more useful.
Only, don't tell me that crystals deal amazing damage... I know that perfectly well... it's just that the AI has gotten smarter and now it knows how to skip turns when surrounded by them (and even more so, the player will figure it out).
