I thought the same but after the M day a lot of people of the X-Men fandom still hating on her (i mean they have the right but Wanda wasn't right in the head and was used as a plot device)
it wouldn't be bad if she works together with some of the x-men in one event or something
but i think she belongs to the Avengers and she doesn't need the mutant/x-men thing to survive as a character
some people even think that the only thing important about Wanda was her mutant connection and her father but i think they're wrong or are not actually fans of the character
I would personally like to see her interacting with Jean Grey
(the original Jean Grey)
