ranked is so fucking rigged this need to stop for real

so i've been maintaining 65-70% wr for like maybe 20 to 40 games and then all of a sudden, one game it's a total stomp and then next game i carry hard asf i kill everyone and stuff but at one point we lose teamfight and then enemy push mid so fast its stupid, my allies keep reviving and getting killed again one by one they get at our nexus i succeed to triple kill alone just in time for nexus not do die then it happen again later they are at our nexus it almost die again but i still manage to save it alone and then they come again and this time i lose the game even if i should have won(4/15/7 jax)

14/7/14 4 KDA 7.1 cs/min 60% kill contribution

next game, all is going well, i destroy asf again but the enemy riven got super fed against our yi top, our ashe is also fed and manage to control her but late game, riven win a fight 1v3 and then she shield for 1/3 of her hp and heal so hard that no one can stop her(8/18/6 yi) and i still have

15/8/14 3.63 kda 4.1 cs/min 63% kill contribution

Its not an individual case, i played long enough to see how streaky and rigged the game is, this always happen, you win forever and then lose forever or else you just win one lose one until the point of madness

THIS IS SO FUCKING STUPID FOR REAL RIOT AT LEAST FUCKING VARY LP ACCORDING TO HOW GOOD YOU PLAY FFS!
