This, just like I said. It's not valuable, long-lasting content. These people asking for it will only spend a small amount of time with them. Scrap it, work on chocobo raising/racing and other content instead. Those systems build on existing content and expand it, rather than making disposable, tacky COLLECT ALL TEH MOUNTS content.
When Square releases these, I hope there is a DAT mod (or even an official option - YES PLEASE) released swiftly made to turn them all into chocobos. That way those of us who didn't want this crap in our game don't have to see it.
