1) Something about the Desert Mudhorn mount felt off to me and I think it's because it uses the lizard-like wide-splayed stance and crawl animation, the same as a Dewback for example. As a rhino-like beast, the Mudhorn should have more of an ungulate gallop so I think using the same animation as the Uxibeast mounts would be more fitting.

Run comparison
2) Does anyone else think the Basilisk War Droid is more iconic as a flying-type mount? Maybe they could split the difference and the current walker animations for standing idle and toggled-on walking, but have the run animations be floating with take-off and landing animations.
