I had the same feelings initially, but I gave it time before actually forming an opinion.

I've cleared 12 times now. It's not really that bad. It takes a while to get the mechanics down and be consistent, but once you do, it's got a good flow to it. Just need 7 other people that have it down, and in a [Duty Complete] party, you have that. Every farm party I've setup has just been simple clears. There are often lots of silly mistakes (that all players there normally do flawlessly) but we're all good and patch them up somehow. I've never seen enrage, not even once, not even in prog and not even with lots of deaths.

It's a fun fight. Once you have it down, it feels right for the person it's representing from FF9. I even dread getting the mount almost because I want the experience of doing the fight more. If you don't want to do it much, you can always unsync farm it in the future. Even later within this tier (7.3 patch) we'll be skipping so much more of the fight in the right party, and won't need to even save LB3 for the tanks.
