I played doom bots a lot to get the icon but it wasn't very fun to do. I gave up after 4 games because it just sucked. You were forced to play certain champs to win like brand but he was disabled because I guess they don't want you to win. They choose "Hahaha, funny" over the "Fun" Aspect, like a game should be focused on. Because the Funny part just turns into rage after 2 games.
P.S. Also stop doing Acension because after you changed it, it sucks.
