I can't find the response but one of the Leads posted an explanation for the queuing with your chocobo out problem and stated that they ARE working on the issue but they're trying to figure out how to do it without taking away any of the advantages of having the chocobo out. Plus they can't demote the chobobo to a pet or you'd open up the possibility of having an 8 man party with 8 birds. Basically they need to find a bug-free way to program it.
