With pets up until now, we had one pet summoned by one skill, so there was generally no reason to unsummon. However, with the new Raise Skeletons ability, it would be really groovy to be able to unsummon a pet with a targeted ability or at the mouse cursor location with a universal ability similar to Pet Attack. That would enable us to rid ourselves of baby skeletal warriors when we’re going for something stronger or more specific. It could also help get out a mage army if the player is focusing more on fire pet damage, etc.
Micromanaging 8+ skeletons might be a bit of a nightmare for most, but once we get high enough level pet gear, player level, and skeletons themselves, they might last long enough for us to get out our desired setup and leave it that way for most of the gaming session, save maybe nemesis and boss fights. Plus, those who don’t really care to micromanage can simply not use the ability =).
