I would say that no one should really expect any long-term, difficult to complete content until after 2.0. Right now SE's goal is to make 2.0 amazing, and keep subs in the meantime; so until 2.0 they're going to be throwing some fun, short-lived content at us to keep us happy and (fairly) busy.

I think the Moogle fight is really fun and appropriately difficult, and really the only issue is avoiding obvious exploits in the future (reset-strat, wrist flick, etc) to make the content more legitimate. Right now I have low expectations, but when 2.0 hits, my expectations are going to be extremely high.
