Like I said, the abilities don't matter. Fiction is about characters and their interaction. What matters isn't what they can do, it's who they are.
Come now; of course
abilities matter. There's a reason the X-Men don't all
have healing factors and claws as their sole powers; in the superhero genre, a generous variety of abilities is inherently more interesting than the dearth of same. Moreover, "what characters can do" inevitably shapes and defines "who they are". Just ask The Thing, or Nightcrawler.
Obviously, abilities aren't everything, but we're not exactly talking an almost purely intellectually-driven milieu a la The West Wing
