Not only is it slow and annoying, forcing you to look at the entire animation, but it also massively lags the game.
Solution: Get rid of it, because it adds noting of value, on the contrary it just annoys people, and just add a simple text message instead telling you whether you’ve been defeated or victorious.
Later edit: if you lose you are also have to watch the slow and laggy banner animation twice, once telling you “eliminated” and once “defeated” as soon as your team loses.
