There is no one way to develop a character. Losing can be just as important as winning when it comes to growth. Seriously, this is much preferable to a MC that never loses.
Yeesh. I would kill myself if I got humiliated like that. The worst that ever happened to me in a performance were only minor mistakes that casuals probably don't hear. This is why you should practice once or twice with the group before performing.
