So, I was giving it some thought, and realized that the mechanical side of the operator; we have a lot of threads dedicated to the customization and aesthetics of the minions in question, but we don't focus a lot of the mechanical side of those powers, so I figured we might want to address that. From what I could figure out with some discussion with a friend, there's four overall "types" of minions, and three design strategies they'd work with. This'd make choosing your minions essentially a two step process, even before getting into appearance customization and aesthetic decoupling.
First, determine their role. There's three clear roles that Minions can cover, though the developers could possibly choose to include more:
--Assault (A mix of Melee and Range)
Second, you have four options for what the minions are:
--Automatons (robots, golems, undead, that sort of thing)
--Humans (Military, thugs, ninjas, etc.)
--Animals (a pack of wolves, a pair of lions, a wyvern or chimera, etc.)
--Summons (This'd be energy constructs, demons, elementals, and the like)
The purpose of this is twofold; first, the nature of the minion determines how it behaves, such as morale effects and overall intelligence. Automatons and Summons, most likely, would be on the low end of that scale, while humans and animals might have somewhat more tactical awareness, move to flanking positions, and that sort thing. The second is that it applies as a defensive powerset; automatons would have high psychic and physical resistance, but may be weaker to elemental stuff, while animals would likely be strong against hot, cold, and physical, but weak against psychic, poison, and electricity.
This would also have the additional benefit of essentially letting you do these in a similar way to the player characters themselves; that is, Primary and secondary powersets. Not too complex, builds on what already exists in the game, and gives the player additional control over how their minions operate, which is all good.
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".
