Would anyone else like to see Barton cause a big loss in SHIELD agents directly due to his actions or a bad judgement, and then sort of distance himself from SHIELD? Like, possibly getting (if they introduce her) Mockingbird killed in action, and what he's done possibly leading to him leaving SHIELD and becoming Hawkeye? He could use an altered version of his Avengers costume (without the Shield logo) and have some sort of cowl. And of course, make it some shade of purple.
Hope it's not just me
