Mastery points from bot games

I think it'd be cool if people could get champion points from bot game, just have it reduced since you aren't playing against people. You could give 1/4 or something of what they would get from a real game, I don't know. Having the champion score, S+, S, S-, etc. would show new players how they're doing, and would tell them if they're getting better. Getting an S shouldn't count toward toward your actual champion mastery, people would get S too often for that. I just thought it'd be a neat idea.
