My only problem with reporting bugs in a game, despite knowing how to report a bug and playing a lotta games, is that I don't always have the knowledge a thing happening is a bug and not the intended design. It's not like I, as a regular every day player, have insight into what was supposed to happen that would indicate a bug.
Obviously a bug like my guy doesn't jump despite pressing the jump button is pretty easy to recognize. But how am I to know the damage calculation is fucked up when I'm not told what the formula is supposed to be?
