And how does screaming at someone for being bad all game help honestly.
I admit I do bad heck im currently suspended for going on tilt hard, a lot of players I play with do bad sometimes, but if I raged at Lux for costing us the game when I carried the game hard, How does that help us.
I am sure its bad enough that they knew before that they likely cost us the game, there isn't any need to punish them for playing badly because i watched them playing the game and they did their best.
Instead of yelling at someone for being bad why not try to help them if you have the ability to help?
