I'm not sure myself if the Moogle of Glory will be worth the effort in the end. Its greatest strength is that you can use every deck with it (obviously) and its stats are progressing really fast compared to the other Keyblades but since the support for it will be discontinued after the event its usefulness will end with it to, as the other Keyblades will get stronger and it will never be featured again.
If there is a potential 3rd Anniversary event there will probably be another Keyblade too.
At this point I wish that the Keyblade in [chi] had more differences altogether, abilities like in KHII for example, so that there would still be a reason to use it after the event.
All in all this event is horrible slow, even though the mission structure and the special Daybreak Town last year wasn't that exciting, at least you saw your progress with the different gummi ships Donald & Goofy were building.
