I hope so. I didn't like the idea of trading actions for pets, but a minor action makes a heck of a lot of sense. Doubly so, if you assume summoned critters aren't really doing things of their own volition, which is fair. Three seems like a reasonable limit to how many critters over which one guy could exert his will. I'd expect enchanters to have to make a similar trade-off.So this is a functional preview of what 4E's summoning will look like, yeah?
Either type of character might have a power available (per encounter? at-will utility?) that lets them trade a move action to control two critters. That sort of thing creeps the count higher.
