PSA for climbing: Please, DO NOT INSULT YOUR TEAMMATES NO MATTER HOW BAD THEY ARE DOING
The #1 reason is fragile egos and ragers who don't care about winning or having a good game; instead, they want to settle personal scores over actually playing the game. If you say anything about how bad they are, they're just gonna intent feed or AFK. It does not matter that all your other lanes are winning. It seriously doesn't. If there is a troll determined to make you lose, YOU WILL LOSE and there is absolutely no way of predicting who is immature and who isn't.
In a recent game, our mid tells our support they're bad. Our support threatened to AFK, and our mid told him to go ahead. Big mistake. Our support decides that AFKing still leaves us a chance to win. Why would he want that lol?
You want to climb?
Then please, be nice to everyone. Not for their sake, not just to be a good guy, but so you don't get trolled and lose for free.
