Let us have more interactive emotes, like Lúcio's DJ emote, or D .va's Game On! They encourage others to use other emotes and overall make the gaming experience so much more pleasant. Let McCree strum a tune on a guitar! Let Brigitte have a cat running around!
They could do like 3 emotes designed to go together with a really chill campfire song atmosphere, like brig mcree and hanzo, all playing and humming away, to the same tune
