I really love this game, and the devs are great for the most part...
But if there was ever an example of fans not knowing what the hell they themselves want, this is it.
The constant demand for new characters, that 10% of the players know about and 1% of the players give more than a single nugget of crap about is bloating the game with content that practically no one wants or needs.
Seriously wouldn't you rather have more content with the big names: Events, story, scene variations, perhaps even animations, rather than introducing "D-lister-woman #43" and "Obscurita the boring, from that one episode of JLU"?
I feel like those demanding new characters all the time do it just because they are aware of the characters existence, not because they particularly want to see it. Do you really prefer waiting for no-namers, rather than getting content with someone like Wonder Woman, Supergirl, Batgirl, Starfire or Black Canary?
I would rather have 20 well-known characters with 20 scenes each, rather than 50 characters with 8 each.
