More points are already being given away to the 10 wins a week arena "masters", aka 1800. If you want the full points to hang around 1200 rating then u have to do RBG. Why, cause blizzard probably wants more players do participate in RBG.
Question, why do you need the full 2200 conquest if you clearly arent doing anything with the gear? You dont need 2200 conquest points a week at sub 1500 rating.
