In the IEM Rio Major that is happening now, the brazilian crowd are helping the BR teams, but not only supporting, they are directly interfering in the game...
Whenever an opposing player infiltrates or is going to kill someone from behind, the crowd screams a lot and the brazilian players have already realized that whenever the crowd screams its because something is happening, and if theres nothing in front of them, they already know theres someone behind or infiltrated...
This is shameful, even more knowing that the only victory of a BR team in the tournament, was in a match BR x BR...
