I never understood why we decided to give points for losing. It's like a participation trophy. Yeah you participated and lost, but because everyone wants to feel good, so in order to not hurt your feelings you get points.

Accepting loss is an important skill in the Arena though, it may even be worth rewarding, though I was personally just for no point loss as opposed to points gained for losing.
