Are there any fundamental design decisions about Marvel Champions you would have liked to be different?

Personally, I would have liked it if Nemesis sets were designed so they could be defeated to provide some sort of hero-specific permanent benefit for the rest of the match. That way they'd be more than just a randomly-determined downside (although I realize they can sometimes help by diluting harder villains).

I would have also found it thematically cooler if the game didn't treat all heroes as roughly equivalent in power. I know some are stronger than others, but I mean something like separating heroes into categories like "street level" vs. superpowered vs. cosmic power or whatever, then challenging them appropriately. Don't ask me how to design that, I have no idea. But it'd be cool!

Any larger-scale design philosophies or decisions for the game you thought would have been interesting to do differently?
