Should the X-Men fight with other super heroes? It seems like a lot of people didn't like AvX and the X-Men having to deal with Scarlet Witch as an enemy lead to M-Day. These events don't seem to leave many people happy. The thing is characters like the Avengers have their own fans and so the writers have to balance the wishes of fans of both camps. If the X-Men are fighting someone who is supposed to be a villain (be it a sympathetic villain like Magneto or a really unsympathetic villain like Red Skull or Apocalypse) there is no balance the writers have to strike, the X-men can defeat the villains and no one will complain about the results.
