When will Monstrosity be updated?

2) Square is reluctant / unwilling to expand this content since the majority of players said in on of the polls some months ago that they 'don't like' this content.
(this can be easily rectified by adding some form of party mode though...)

Actually, as I recall, the poll showed that the majority hadn't even tried it yet (I would assume that was because there was no reason to do it. I.e no good rewards, no real PvP, etc). A much smaller minority had both done the content and didn't like it. And that goes to show how much of a home run SE had in there hands with this content: That even with Monstrosity being as incredibly limited as it was, the majority gave it a positive review.
