In first place , sorry my english is not fine 
Any heroes are less strongth than should. Example : Magneto should have a cover of 4*, and Xavier 5* Between others heroes.
The recent movies have better heroes … is “normal”, but think what the game is not a film and would gain addiction.
That you think about it?
PD : Have some ideas for the heroe power, if you want we can comment on them
Magneto was released before there was more than 2 4s. The 3* game was the pinnacle at that point, and magnetos original powerset was amazing. He’s still a great 3, but he got hit with the nerf bat a couple years back and isn’t the powerhouse he used to be.
Professor X was an early 4*, and the first 4 with 2 passives. People complained about it when he was released, saying he’d be useless, but he turned out to be an amazing support character even well into the 4* meta.
The reason they won’t make new versions of PX or Mags is unknown, but right now Marvel games don’t have anyone from the X-Men license. It’s not just MPQ, it’s other, much bigger games with way more money behind them. People suspect that Fox is holding that X-Men license close and not letting anyone they don’t own use it for anything.
But if that changes, I’d love to see a 5* Magneto and Professor X. And then Gambit and Rogue and Negasonic Teenage Warhead…
