I'm a demoman, but I can be a temporary pyro if I'm using a poor textbook, my teacher is horrible, or I legitimately did not deserve to lose points on an assignment. But the thing is, when I end up criticizing a textbook or teacher, my classmates wholeheartedly agree, and when I bring up problematic grading, I get the points back. I don't turn in cheaters though. They end up failing and retaking anyway.
