Toxicity is such a problem here
By "Here" I mean on the boards but especially in game too.
Your jungler ganks, tower dives, gets killed & you go off at them acting like that's never happened to you. I've been executed before. I've died in 1v1s. I've had failed ganks before, I've died in 1v1s with their support, Hell, I've even been executed to raptors before. And so has everyone else. Everyone has a bad game once in a while, where their opponent just outskills them. It's no excuse to verbally abuse that person.
I mean it's just a game, you're not going to carry every game you join. So instead of flaming at your teammate, you coult try supporting them to do better / giving them advice. :)
