welp i lost a ranked game and im taking a break from this game

i just lost a ranked game we could have won but i ks a xin once and he refuses to help team after that and pushes side lanes everyone tilted including me none of us played as well as we could have because xin got one kill stolen i hate how one player can take a whole game hostage and ruin it for his teammates its so annoying im taking a break from this game im not enjoying it i may be getting unlucky with teammates but it feels like the every game is like this and one person decides to ruin it for their team im coming back later i hope it will be fun again
