Yes, but the problem is that the incompetent players in the match don’t leave, so you are stuck in a losing battle with them. So leaving for me does nothing.
So you’d rather stay on a match where you know the stack has the lose mentality and they’re going to drag you into a lose anyway? Because no matter what you do, you can’t win 1 vs. 5. 
Again, this is not a game where one person can win alone. “team-based” game.
