I'd like to see something like this but not at all for Duty Finder. Inflicting your chocobos on some random innocent stranger is just too cruel.

If you just want to get a newbie or alt through the easier dungeons and give them time to learn the job and you don't have enough for a full party getting a chocobo to fill that last slot would be a pretty nice alternative to someone who just queued Duty Roulette to get their tomes and wants the dungeon over as soon as possible. You'll probably be wiping more than once but that's what a learning run's for anyway.
