The JP players must play FL way different, cause I've played on all 3 GCs for the pony and the thing their pugs all had in common was a mutual hatred of their own GC's players and a constant paranoia that the other two teams were in some collusion to team up against them.

In the end I don't think anything will change for FL. They'd probably just make a new mode that is not connected to GC if anything. Right now the GCs are tied into the queuing structure, score screen, the achievements, the mounts, map doodads, lodestone, etc. If they can't even make it so you can queue with a chocobo out, I don't think they can untangle the web of code for this change without just making something new.
