I can't disagree with this.
thats the point.
the 70's roster is poor, as good as McAvoy, Fass and Lawrence are. This is their second movie already, so they need some new blood to interact with. And no, just Wolverine is not enough. We have already seen Wolverine having scenes with Xavier, Magneto and Mystique.
The 70's need new stuff and relationships to give us something new and again, to expand the 60's world.
