You got to be kidding right? Would you want to fishing while on Chocobo too? Or gathering while on Chocobo? Or better yet craft while on Chocobo? Chocobo is a mount, it get you from one place to another. If you can do everything on Chocobo then it like making everyone walk the speed of a mount.

If you mining, just hop off your Chocobo and mine. Stop asking for everything to be giving to you.
