Eh.

I'm on the fence with this.

I mean, if the game is well played and we still lose, yeah...but if we lose because lack of roles not performing as they're intended to (that goes equally for dps/healers/tanks), then I don't think praise or "good try" is deserved as it gives a false idea that the team played well.

That being said, if people performed poorly calling them "crap tier players" or the like is all but constructive.
