riot's matchmaking is giving me migraines..

riots matchmaking is absolutely fucked up. im climbing get to promos and i get 2 first time ranked players 1 player who is good and 1 who is tilted by champ select.. both first time players go 1-8 and ect the tilted guy just trolls after he gives first blood and that leaves me and the other player who are trying to carry 3 awful people against 2 duo's and a last season plat player.. now if this was just one game out of say 20 id say shit happens.. but this time of player matchup is almost every other game. the game is decided by champ select almost. my last game as Ashe i jump out to a 4-0 start by like 9 mins. meanwhile my first time ranked zed mid laner goes 0-6 vs a tf.. brain dead GP goes 0-4 * all 4 kills go to a kha zix * and our rengar ignores objectives.. kha zix was 10-1 at 15 mins from zed and gp.. at that point im a one shot waiting to happen. like honestly how am i even supposed to carry that lmao. 2 different promos in a row ive lost games where i had 3 people who were either 1-8 or worse in the same game.. even had a 1-21 bot lane at 17 mins.. tf am i supposed to do when i get teams like that?
