That's the type of players I encounter sometime in my games. Sometime against me, sometime against others. I like playing League of Legends. I really do but it's hard to play when someone insults you really badly just because of a bad game. Maybe you lagg, maybe you are trying a new champion. Maybe it isn't your day. XD
Show a little respect. This world needs respect so badly.
It's a game you play with other people. You will not insult them on the road. Do not insult them on thie game.
And as for Dunkey, that I didn't know since this story starts, fine with him for not wanting to play league anymore. Tough, countless of players who get ban in the past improved their behavior and are still playing. He just needs to grow up. Tough, with his behavior, I think that stoping League for a while will be the best thing to do. He seems very on tilt. He don't seem enjoying the game anymore.
P.S.: Sorry about mistakes in english.
