This is a huge part of the problem for me! Imo all map zones should function more like Eureka/Bozja as a baseline. I enjoyed both iterations of the idea and was hoping, as with all things, that exploratory content would have been continually refined instead of just shelved for a whole expac. Bozja content was great but I found the subject matter and story delivery very dry - a personal problem I have with Matsuno's work although I love the pomp and weight of the dialogue in the ivalice 24 mans] - it also didn't help that the whole map was a desolate, craggy warzone. The sequestering off of these cool open world systems into their own separate content really kills any incentive to commit to them in any meaningful way even though they provide a far more structured and integrated experience than the baseline overworld. Bit of a waste tbh.
