I think as long as they view Cent as a lifestyle product, they will continue to offer as little as they cAn get away with. I once raised it with someone 'high up' that getting better rewards for spend on the SPG -> Marriott Amex cf. Cent made no sense, given the former AF was like 3% of the AF on the Cent. They were like yeah, but Cent is lifestyle blah blah

Have also previously raised that should be double MR's, if not on all spend then at least in particular categories or on everything above, say, 100k. Response was MR's cost them a lot, but they would report my feedback.

sadly, I will probably just end up renewing. 1st world problem, but still.
