Apprently I was told by another user that "The autors have already told (and it was clear in the page you mentioned the Storm quote) that the X-men don't fight quite often in this reality. They don't have to. They live in peace, in an Utopia. Nate doesn't allow villians to exist, I imagine. So, if they don't fight, they get rusty. That's why Storm seemed purposely weak and Magneto and Kurt even improved the argument with their lines."
