Why the fuck do you get less mastery for losing?

If you win a game with a good grade, you're likely to get over a thousand, or half a thousand. But when you lose you get almost nothing. I got B grade, and how much did I get? 181...Idk, I'm just trynna get my Anivia to Mastery 5 and this shit is really frustrating when you're leveling champs to 5.
