Not voting for rmk is, lets face it, retarded. If the game is 24-1 it lost it's sense even for winning team. I know that most people find very funny to killing defensless heroes. If one side has huge advantage the game should be rmked or very fast finished (very fast means 3-5 minutes).
This ofc counts only for already decided games. If the loosing team is defending and remains rmk,then no rmk should be make. Also i've ecnoutered sentinel team who demand rmk when score was 19-12 for sentinel.
