From my experience, the fight itself is still Amatsu. Thankfully, they didn't, imo, "ruin" the aesthetics of the original fight by copying the Dragon form from Frontier, but MHO Amatsu did borrow the ground slam move that causes a ring of geysers to form. Along with that, Amatsu has a new sweeping laser. Needless to say, everything looks pretty good visually.

However, Amatsu was changed to use it's 2nd Phase theme while it's enraged (Like Caeserber and Taikun), which really just messes with the tone of the fight. Along with that, most offensively, clearing the quest uses the regular MH2/MHFO/MHO Quest Clear theme, and the storm around the map doesn't clear. Also, I noticed that Amatsu tends to stay still less, which makes the fight pretty annoying for Blademasters. There are ballistas in the area, but there's no way to get ammo as far as I'm aware.

Overall, the fight is passable, I guess, but the most iconic part of the fight was removed, which is beyond disappointing.
