I love this idea.

Whenever I see someone new drop a Tag Team roster sheet, no matter how cool they are or even if they drop a killer debut RP, in the back of my head I think, Welp, they're going to hit a ceiling, for exactly the reasons outlined in bullet point 1 above. Which is a bummer, cuz it prevents a lot of cool, designed-from-the-get-go tag teams and rewards pretty exclusively those Mega Powers-esque duos of solo characters.

Pretty much any idea that rewards tag teams for awesome collaborative effort, instead of excellence in isolation (which is awesome, of course, but not necessarily a celebration of what the tag division is), I am 100% in love with.
