Especially with stuff like December's double digging campaign, and the dev time spent adding dig loot to zones along whenever they add an area that mounts can be used in, isn't it about time that "Chocobo Digging Skill" be added to the character crafting skills window?
It's definitely a "skill", and definitely tracked by the system already, so why hasn't it been made visible already? The inability to SEE your own progress is probably one of the big turn-offs from doing it for a lot of players.
