MGP's just too easy to accumulate if you know what to do (80 score Fashion report + enter and concede in the Verminion tournament + challenge log), but many players don't even know that much (you even see people farming Prae during moogle tome events for a pittance in MGP) so you have a sort of divide where to the majority a million MGP is a lot and they're still saving for rewards, but the remainder of us have been MGP capped most of the expansion.

They generally cater to the majority and the Sabotender mount is probably about as good a bone as they're going to throw us.
