I know that currently the in the MCU....The Avengers are currently not active but...still. I hope that Cap 4 ends with Sam forming a new Avengers team.
But finally to the topic at hand. Think the Lagos fight for example. The Avengers are casually taking on some terrorist that want to steel some experimental stuff...low stakes, characters bantering among each and etc (I know the scene is very important to the movie as a whole as it sparks the entire Accords conflict...but humor me for a sec)...It makes the MCU feel more alive and less static Imo.
