Why would 'all hell break loose' if that's the case? Why would anyone care if something exclusive to those who could genuinely attend isn't globally available? This has been the norm for as long as there's been fanfests, not just for Square properties. Minecons gave out exclusive capes for attendee's Steves. Blizzcons gave out... somethings. So people attending Fanfest get a mount. Big deal. It's not like any of the mounts are mechanically superior to the rest. Seriously, when did these generation of entitlement begin? HOW did it begin?! Are parents really this stupid these days?
No, the only reward for finishing 2.0 is a title and the magitek reaper mount. Unless you mean 2.# which even then, no. Odin's part in the storyline is in the form of 2-3 quests that serve no better purpose than to say, "Oh, hey, you're level 50, there's a fate out there that lets you fight Odin."
