She could stand on her own and be an inhuman like she has been for these past couple of years. Are her powers going to come from a family heirloom instead of her metamorphosis? Maybe. I see her inhumanity as something that's a part of her character because it was her awakening. I understand that a lot of people dismiss it from either a bias, or they detach the character from her origin because they don't care. Was being a mutant really important to Wanda Maximoff? No, and her magical aspect is more interesting, but I still think it was interesting having a mutant that wasn't related to the intellectual property of the X-Men be a member of a more inclusive team. It made them appear to be more dispersed in the world.
We'll see what happens. Maybe she'll be the new Quasar.
