One thing I'm seeing a lot of posters misunderstanding is that the Hulk-Hulkbuster battle took place in Wakanda. That was NOT Wakanda where the battle took place, Wakanda is a HIGHLY secured and fortified nation there's NO WAY The Avengers would've been allowed to just stroll into Wakanda and and have a big ass battle, putting hundreds of Wakandan citizens at risk without T'Challa appearing to murk them all.
