Clearly the easiest solution for Marriott at this point is to introduce 10 new award categories and devalue the points values. Then they'll e-mail all the people that complained that their current cat7 doesn't give them a new cat7 with "HAPPY NOW?" and they'll have no valid ground to complain, since their old cat7 still does, in fact, remap to a new cat7. And they also saved themselves a bunch of money because it'll only be redeemable at Four Points. win-win!
