Truthfully, Xavier was always questionable, that said there's at least a dozen better ways to had written him out the X-Men. I've always had a soft spot for Charles the animated series and movies contributed to that, but he could be used in better ways.
There's a lot left to and to go with him, always liked what Carey was doing hoped that carried over or across other series. I'm ambivalent towards "X" not sure if in time he'll casually transition into Charles without much fare, or remain this new character.
