that would make players care more about their players experience
Actually nobody seems to know exactly how experience works (some say its just minutes played, other sources show its pretty random) - If you dont know hot to influence experience its better not to care about it at all and if its random it should not be rewarded.
From what Charles said, its about decision making. But if player doesnt have skills, his decisions will be always wrong, because in the end are his skills just too weak.
So I think would be nice if some skills would pop-up with XP in some way, so we could see that player got something from the field and it wouldnt be just about respectable veterans anymore...
