Are you tired of Iron Man being overexposed?
Here's some facts to consider in your answer:
Iron Man has had 5 appearances spread over the 7 MCU movies.
His 5 appearances have been spread out over 5 years. That's statisticly 1 appearances a year.
Conversely the rest of the team; Thor, Captain America, Hulk, Black Widow & Hawkeye have currently had 2 appearances over the 7 MCU movies. That's statisticly 0.3 appearances a year.
Iron Man is currently (not certain on this) the only confirmed character for Avengers 3.
Tony Stark is reported to be the creator of Ultron for Avengers 2 so his role will have to be more substantial than the other team members.
