Well... that boosting wasn't exactly boosting, because you get less credits than just playing regularily. It's only use was to get commendations to onyx. Oh, and the reason you stopped getting credits was because after a commendation reaches silver (campaign only), you recieve no more credits for individual advancements of that commendation. -KidVegeta
