I m new to the game (33 lvl Black Mage) and i noticed when i use my Chocobo i cant queue in Duty Finder.
Queues some time takes up to an hour, so in the meanwhile you are forced to play without your Chocobo while questing. Is this something that offers anything to the game play? I find it rather annoying.
Choco's aren't real players so why not having with you as long as you wait for a queue to pop? Anyway they are not going to enter instance with you.
I hope this restriction to lift sometime. In the expansion maybe?
