While I know it may be too much to ask that they dodge attacks, it seems appropriate to me that Chocobos who are healer stance, act like healers, and keep distance between them and mobs. Having a choco right behind ya means that you hafta overcompensate dodges to keep him from getting hit. Maybe even a "stay" option, like you have with pets.

Anyhow, just a thought. I'd be more apt to solo Alexandrite maps if I didn't hafta worry about resummoning my healer choco.
