Riot need to come down harder on arrogance
I think that people who go "Ezi" or "You are crap" etc should recieve worse punishments from the punishment system then they currently do. Doing that is the height of bad manners. Be happy you won sure, but there is a fine line between that and arrogance and as with most French players in this game, its basically what a lot of Europe has in spades.
Arrogant players need to be crushed out of league just the same as toxic ones.
