It's really just the new 24-man raid that's FFT themed. It's a fun time, and beautiful, but I don't care about Ivalice. Never have, doubt I ever will, so it's wasted on me.

HW 24-mans were the best, because they were completely original content, and the story was relative to FFXIV exclusively. The only throwback was there was a cat character named Cait Sith (who has a completely different personality than FFVII Cait Sith).

Tbh, a lot of content this expansion has been lazy reskins of old FF games. Which you expect to an extent, but too much of it is lame.
