A serious troll
This player is a serious troll, you can see from his statistics he is just playing league of legends in order to make fun and ruin other peoples day.
He basically mains anivia
and uses his w in order to block you and let enemies kill you.
I would be glad if this player got banned from the game since people like him are really inappropriate and shall not be playing this game.
His profile -no naming and shaming-
is a huge troll problem Riot most rework they abilities to apply block on the enemy not ur teammates.
