right but you see that the only way to have them avoid crossing paths is to conjure up mumbo jumbo. you can't keep the avengers off earth for the entirety of the x-men run, unless of course you kill them and have the x-men take the mantle.
if they were included in the MCU they wouldn't be able to help themselves, there would be a spidey/iron-man/hulk cameo every other movie.
an x-men movie should feature the x-men.
So you think there wouldn't be solo X-Men movies? There are crossovers, but outside Spidey, who hasn't had his own movies with their own casts villains and storylines? The hulk, bw and Hawkeye. Major avengers though? Theyve all had their time to shine
