What sort of criticism?

"Teemo ur bad stop playing uninstall" = harassment and flaming

"Teemo try to lay down mushrooms in baron area and use move fast to run over them if they start to collapse on you" = constructive and fine.

Actually any of these are fine by me:

"Stop split pushing and group as five"
"Lay down some mushrooms so we can kite"
"Stop building AS and build some AP so you do damage"
"Don't wander into enemy jungle when you don't have vision"
"Don't facecheck bushes when you have vision on one person"


Even more aggrivated ones like "STOP FACECHECKING" and "MY GOD DO NOT BUILD RAVENOUS HYDRA" are not going to make me hit punish without it being sustained and consistent.
