No, if i want to use my unicorn over my chocobo, it should be the same speed, its aesthetic. By that logic, the legacy chocobo would be the fastest mount right now, and I'd only ever use that because why would I want to get some place slower?

I think mount speeds are for games that need even more money sinks, or have cash shops, giving people incentive to spend $5 on a mount now that sucks, and later on have to upgrade to a decent mount for $10, etc.

By making them all equal it says "choose aesthetically what you want", I like it that way.
