I don't have much experience with the game, but I'd love an option to “pause” paying certain minions so they just go into infinite sleep or whatever until you start paying them again.
This does however allow to amass minions and then go in a huge pack, so that'd need to be addressed. And it also creates a whole new spectrum to balance.
It'd be nice, but I don't see it happening without major rework which wouldn't be worth to simply allow certain people to enjoy a play style they enjoy more than the one in place.
So, I don't think so.
