You chat ban me for getting stuck unfairly with constant teammates that feed and troll and afk and I'm not supposed to get mad?
What does getting mad do? Do you believe you typing to them will magically make them perform better? Newsflash, it doesn't. You are far better off to just mute+report and move on. You do realise that on your team you can only get 4 of those ''bad teammates'', while the enemy team can have 5 of those if you truly yourself perform better than the rest.
Also you accepted the terms when you created your League account, and by breaking those terms you got punished with a chat restriction.
but I'll never get out of bronze hell as solo Ranked because this game is a cesspool for toxic trolls.
If you can't get out of Bronze solo, then you aren't good enough for higher ratings. If you truly belong to a higher rating, you will eventually climb if you put your mind to it and have the necessary skills.
