spamming your emote in a 4v5 should be a reportable offense.
Had this yasuo whom spammed his emote in a granted win when his lane got crushed, and the only reason he won was the enemy going afk. In all decency, I think making people disconforting in their most harsh time is a act lacking of decency and manners.
He said in his defense it is a mental game, but isnt it just him which is mental? rubbing granted wins that just happened to fall in your lap for free in the enemys face is not playing pshycologic. its called being stupid.
