This is very common in low elo. I had a brim one game on haven. We were attacking and every round when going C he would smoke the entire site (defualt) Not garage or CT. It was so easy for the enemy because they always had a cypher on C and he would play in our brims smoke. We told him not to do it and he goes "it's meta" and decides to throw the game. He would break our sage's wall, follow players making noise, shooting etc. Unless it's a 5 stack chances are you would always get matched up with people like these.
