This isn't a major game changer, but I think there should be an option to play with one of your earned hats chosen at random. Like, I could play one round with a melon head, and the next round with an Ender Chest without having to open my menu. This will be chosen from the hats you already have. I think it will be useful maybe a player can't decide which hat they want, or they want to avoid getting targeted (similar to stream sniping) . The hat would change every game. If possible, maybe this could be done for armour too.
