I am of the opinion that naturally if you die, you don't get to call out your teammates for doing "bad plays". Rather nicely give constructive criticism should they ask for it. Not everyone wants feedback of their play, and getting told they sucked is a surefire way to get people to never want to play again.
As for the queue, I can't make them stay. If they're busy or unhappy with things, that's just the way it is. :/
