I think a great archetype would be a necromancer. This archetype would rely heavily on the use of minions. I think a game that really did a good job at implementing this was City of Villains, specifically the Mastermind archetype. I think it would be awesome to go on the battlefield and have your own mini legion, but obviously it would sacrifice your personal damage abilities. The balance would be that your personal powers would be mostly crowd control based. That way the majority of your damage is reliant on your pets, making them less of a "nuisance" and otherwise harder to ignore.

Here's a video clip of what I'm referring to:
