LOL you and everyone else, so far this live umbral events has been extremely underwhelming,they played us good with the promise of content though. /sigh, seems SE were just after our money as usual.
I was expecting more then what we got, but nothing near what other people were expecting. I expected a bunch of little 'achievements', an occasional item or two that you could only get during the events and slow but escalating ramp up to 2.0 of the live portion of the events. What I don't think people understand is that part of the 'only can be seen before 2.0' stuff is also the one shot GC quests as well as some of the battle rewards from things like the primal battles and such. From what Yoshida said during the second live producer letter the primal battle rewards might actually be only available (In their current form) before 2.0 since the battle themselves will be changing slightly for 2.0, both for story reasons and even slightly for aesthetic reasons. Yoshida mentioned the primals would 'look' a bit different in 2.0 and we already got a hint of that with the concept art for Leviathan.
So in a way almost all the new content is "Can't be repeated in 2.0" stuff because even if the instances stick around for 2.0, there is no guarantee the gear or the CS leading up to and within them will stay the same. The may very well get tuned for lower level or even new max level fights later on with completely different rewards for 2.0.
Edit: As for the maintenance a JP rep posted the changes going in. We are getting the class/job balances that were said to be coming in 1.22b. Looks like the balances are all in relation to the 5 melee classes and they will balance not only job skills but even some class skills.
