Like i climbed to silver 2 earlier this season, yet im back to silver v, ive been stuck winning one losing one for some time, now, had a bad losing streak, gone back to my best mains in panic, and even now, i can't do shit, its like all the games are rigged for me to lose, right now, im on a fucking 7 lose streak never got demoted to bronze this season, got close at some point but i came back off at red level , it happened to me 3 times tho in season 7 but its like a pattern, as soon as you get the yellow warning, everything become a shitfest and there is a fucking too high load of uncarriable games, pls fix this riot, thats fucking tilting as fuck getting forced to carry the uncarriable, and knowing you are gonna lose no matter what you do
