I don't think this is an issue. I got Bozja and Eureka mounts before this content dropped and I feel happy for people who can get some mounts they couldn't get through sheer RNG bad luck or time commitments. I did over 100 Dalriada runs and I never saw the Deinonychus drop, a friend gave me one, so if it means people can get these mounts easier, I'm all for it. Sooner or later they'd have shown up on the moogle treasure trove anyway.

The mounts are just a low drop from content that takes a while to do, hope to win it from bunny chests, spam dalriada, spam DR (sit in que for 10 minutes), it gets boring after x amount of runs. I don't mean this aimed at you, but I have seen people in game complain about it and for the most part I think they are just upset about the fact that the prices tanked or that their "prestige" is lessened now.
