That's the problem I'm talking about Phase 2 of the MCU, there is literally no team-ups. For instance, in Iron Man 3, Tony and Rhodey would definitely welcome Captain America and SHIELD's helping hands but they kept going about how the Mandarin is a matter of national security and not a concern for the Avengers, umm...the guy is called Captain America and the Mandarin is terrorizing America, why didn't Cap help his buddy Tony?
And where is Iron Man when Thor is battling Malekith in London, Iron Man could easily helped Thor and Jane with his brain to open a portal here and there but not to avail and Thor was left hanging with Jane, Darcy and Erik, oh and the Intern.
In Winter Soldier, we got the privilege to meet Sam Wilson and Cap did get much help from Falcon, Black Widow, Nick Fury and Maria Hill but could you guys think for a second and guess, where is Hawkeye? SHIELD would need they're entire agents to help them right? But where's the sharpshooter?
Yeah, in Civil War, we can see almost all of the Avengers battling each other and in Ant-Man we can see Falcon fighting the little guy but what about after Civil War, will we see any Avengers making a team up in Doctor Strange, Guardians of the Galaxy 2, Thor: Ragnarok and Black Panther before they eventually team up again in Avengers: Infinity War Part 1 because if they, at least make a little team ups here and there, then what's the point of having the Avengers if they can't rely on each others?
