WHY FLEX 5vs5 is taken the fun out of LOL

Why did you guy mess up league I have friends and now I have to play with one of them or play flex and if I play duo I get dumb ass fucks who think there the next faker or lcs pro mid they have cost me hours of time made me drop rank so many times I cant count anymore.

I had spent all last season building a ranked team and a group of friends online to play with it was all for nothing you guys have fucked up the fun of playing this game with the new bull shit system and fuck the fans over what building lcs teams or some bs I have spent over 500 bucks on this game in the past year almost so this is bullshit.........
