@Meddler Bad teammates if high winrate

Does someone know if this is a thing? Do you get put you in a team with players who have recently shown to be a lot worse than the opposing players making the games unfair and reliant on your ability to 1v9? Those players would get solokilled 3 times within first 10 minutes be down 100 cs on the enemy laner even in favorable matchups? Its gotten to the point where I pretty much dont win games unless I demolish everyone which happens rather frequently but it shouldnt be that way regardless. They want to bring you closer to 50% winrates so no one feels inferior compared to players having higher ratios. Im sick of losing games in which I have 20 kills and more damage than all my team combined fix this BS riot. Every time I check on opgg the enemy teams up 100mmr on average ( not confirmed to be true but I rckon its failry accurate) who have way better winrates than the unfortunate free losses that are my teammates. I also get matched vs re t aded 3 man premades way too often with my team having no single premade not even duo its ridiculous how far they go to bring everyones winrate in line. Season 6 rank is meaningless 2 people sharing the same border are actually 10 tiers ( yes) apart and I am not talking about smurfs. Thats because re ta r ded no skill eays to play champs like soraka and janna exist which ge you to too high an elo with minimal effort resulting in vastly discrepant macthups.
