Indeed, people say they want more content, yet the most obvious way to introduce long term content some rather dull it down to almost nothing by allowing every mount to jump/fly/whathaveyou lol. Yoshida is obviously interested in personalized chocobos, no idea why some would be against breeding chocobos to gain certain traits like Jumping/Digging/ability to cross water/"Hot&cold"/flying etc.

Though it seems people aren't against the idea of them fighting with you in battle so go figure lol.
