FLEX MISSIONS?!

why would you ever have missions revolving around flex queue??? Flex is a terrible queue mode that actually makes people hate the game, When you have a game mode that has 4 silvers and a gold go up against a diamond 2 plats a gold and a silver well there is no chance of the first team having any fun which means to finish these stupid win based missions its doing something that is actually toxic and anti fun in the hopes you can complete it. no idea how this was allowed to happen but w,e guess wont be doing anything for clash which WAS an interesting concept but if i wanted to just lose to people 2-3 ranks above me I'd go play CUSTOM games
