the night stalker rage quits half way through. Why is the "safe to leave" being flashed in bright green letters, encouraging everyone else to leave because of 1 rage-quit?

My CM doesn't like supporting and leaves the match too without penalty. Why is this allowed? Now, a match that could have been finished in 30 minutes drags out for 1 hour because the broken system is encouraging more people to leave after 1 person rage quits.
