Idea

If you lose a battle you should still get half the experience that you do from winning. I remember hearing a saying that goes something like "You learn from your mistakes." And by mistakes in our context it means losing a battle. This only works in battles though not training, although I don't know how it would work in training.

Well technically that wouldn't go with the flow of how experience is normally gained on the site. :\

Yeah, this would also make the Exp system have to bring in decimals, which just gets too complicated. The site has had a well flowing experience system in my opinion, and there is an extremely slim chance of it ever changing.
I'm sure we all appreciate your idea though, if you have anymore we'd love to hear them, and certainly take them into perspective.
Thanks. :)
