I dislike the heavy reliance on Ivalice. So far it seems to have been implemented with the assumption that everyone is familiar and will appreciate the references. I haven't played any of those games, was thoroughly underwhelmed by the Ivalice raid series (while overwhelmed by the info-dump they tried to put in so I'd "understand" what was going on), and was looking forward to it being over with.... but now it seems like it's becoming a core element of the world setting and MSQ.

I understand that there are many other elements that reference other FF games, but they seem more isolated (eg. the Crystal Tower - one location on one map). The Ivalice setting seems to be taking up a considerable portion of the world map. It seems out of balance.
