this game made me toxic in 3 days

you know, i have played so so many games out there and i never have issues with people like i do in league. i never have any sort of feeling to get mad at all. but every single match in this game is a flamer, an afker, people who queue up and brag about their 10000 ping. toxic idiots. and then when i start telling them off back i get banned. and im glad. because i need off this game it is god damn terrrrriiibleeeee. coming back after a year and i see a bajillion champions changed. the same bs every match "i dont care" "im not ganking" "i dont even want to win" "my internets bad but i queue up anyways" idc its being stuck in a toxic enviornment for 30-60 minutes and then getting punished if you leave or stay with it. its so god damn terrible in so many ways. which is probably why i dont rage in any other game cause im not forced to sit in a terrible situation or be punished for it. this game by default is horribly designed and im going right back to warcraft.
