I understand why Paquin had a main credit, but I mean her appearance presumably was never intended to be on the same level as the actors who were just secret cameos. And I can't see there would be much of a time / plot benefit in erasing her from action scenes.

Perhaps there was a scene with her attempting to infiltrate the Evil Humans of the future, and thus doing what I complained we didn't see: a plan for the X-Men that didn't involve repeatedly dying or this relatively crazy time-travel scheme.

I haven't seen the second Wolvie solo either, so I'm not sure how it fits in. I think I heard he has the bone claws in that one too, though. Plus I think they're doing a sequel to it, so presumably it's still canon and in line with DoFP.
