I'm done with Riot

Please note I'm not done with League, I'm saying I'm done with the random crap Riot comes up with... I can only have fun for 3 games before some bullshit that Riot miscalculated jumps in my face... Which most of the time nowadays is Garen, Darius, Mordekaiser or Skarner... (notice anything?) though nowadays it's mostly Darius and Garen (in respective to most painful to watch) I literally watched this video https://www.youtube.com/watch?v=4K-0dDPPBd4 after the 4 minutes and it's just sad... Just sad... He doesn't even use his ult it just shows how it's stupid the way that riot can't freaking do his things correctly... It's just insanely sad... Not only that the way Garen is made makes it so it is impossible to focus the ADC when it is time to focus the ADC due to the fact that if you do as soon as one guy dies in your team by Darius... Well say goodbye to any odds of winning cause he'll literally stand in the middle of you while you all focus him 1v4 and laugh at your face... Just... For the love of God fix your god damn game, I know that in the video they all go 1v2 and 1v1 but honestly wtf is up with him living with like under 20 HP against like 5 guys one after the other... It makes no sense I bet he was laughing his ass off at how there was nothing they could do... I love League so much but it's to the point where I wanna play Dota not because of the type of game cause I personally more like League but because Riot can't figure out the correct way they should be balancing things... Yes I'm a noob at the game but heck if there are some champs that are insanely powerful for us low rankers to go against and that the high leagues won't even ban it cause to them it's useless... Maybe we should atleast nerf it so they can become even weaker I mean the high LCS probably doesn't even care what were to happen to those champs and anyways from what I see Garen and Darius seems to be OP no matter what... Though I find Garen somewhat about to be worked around
