As I know, scourge:

-got 70% will lose the game
-always quarrel after feeding in the game
-many noobs
-many feeders
-u can see many players request to be sentinel b4 start game

conclusion is bad, but still I always join scourge with public players, that why always lose . I do try lead the team to have to gank but still hard, use supporter to help them but still dunno fight with killer hero, either in the game all use low life killer then no stunners, tankers & supporters.

Let discus how to control if u r playing with scourge public players & ur experience how to manage it.
