So, we've know a couple things since the beginning - first, that commanders will be a thing eventually, as the Mastermind was a much beloved character archetype in City of Villains (and later, City of Heroes), and that there was no way we wouldn't be having them in this game as well, or at least something like them by another name. It's something I've been looking forward to quite a lot, as mastermind was my favorite archetype in the old game by far.
I've been thinking about it, and I'd really like there to be an option to place your minions inside your personal or group base. For instance, the dragon-tamer's pet wyvern could be curled up in the corner. The soldiers under your command could be lounging on the furniture or cooking or something. Robots could be in workstations having repairs and upgrades done. Stuff like that.
Not everybody would want it for their character, obviously, and it wouldn't have to be there for those who don't want it. But for the people that want a place for their minions to hang out inside the building, it'd be really useful.
Really, adding the ability to place NPCs in general would be excellent, but I'm giving special note to minions because they will be the NPCs that players of a certain archetype will interact with literally constantly.
An infinite number of tries doesn't mean that any one of those tries will succeed. I could flip an infinite number of pennies an infinite number of times and, barring genuine randomness, they will never come up "Waffles".
