Re: Evan Peters Joins X-Men: DOFP as Quicksilver
I'm not sure if this is a big deal or not. They hold joint rights to the character and perhaps by doing so they can imply a joint universe rather than explicitly stated.
I do find it hilarious, those playing the x-men against Avengers card. Who cares how they were used first, they characters were integral to both franchises. The stories of Wanda and Vision's love story was a key arc to Avengers and no one could argue otherwise.
Sometimes fanboys are their own worst enemies.
