Some of the fights were better than others, but I think there were at least a few really good ones.

Hobbes is one of my favorite alliance raid bosses in the entire game. The last boss had some creative moves, and Red Girl did some interesting stuff with the blocks on the boss arena and the intermission phase.

I get the complaints about environments in the third raid, I think having the first three bosses in the 'cyberspace' backdrop area was a mistake. The environment for the last boss was great though, and I liked the environments for the first two raids, but can see why they wouldn't be super exciting for others. I think part of the problem though was that they went too literal. Instead of working these places and ideas into FFXIV's setting they just said 'hey let's put the factory and tower from Automata in here copy pasted' more or less.

The music, the fights, the glams (for the most part) etc I all liked, but the story really dropped the ball and because they weren't doing anything interesting with the story and lore integration, they fell back to just mostly copy/pasting things into FFXIV.
