"New abilities"? "New classes"?
I think you mean "new power sets" (and there's no new archetypes or "classes") and you completely left off the biggest feature: Side Switching (heroes into villains & vice versa).
Edit: Mind you, I'm happy to see it mentioned at all and realize you may not have anyone on staff there who is actually familiar with the mechanics. It just seems to cheapen the site and the game to have such obvious errors.
