I enjoyed all of the ultimate FF14 battles. For the CM I got to use Thancred as a ninja, which is the first time I've used ninja magic the way it's supposed to be used, and it was surprisingly effective, especially that new 5* ninja nuke. I made a bad judgement call near the end of the fight, but Minfillia's last stand limit saved the day by preventing three deaths which would have otherwise been a wipe.
Garuda fight was also kind of fun. I went with my typical team of PCecil, Vaan, Agrias, Ramza, Arc, and with everyone wearing wind resist accessories, it went smoothly. I killed the feathers until the boss was around 50% health, then I ignored the rest of the feathers and focus fired down Garuda. With wind resist and debuffs, her ultimate nuke only hit for around 2500.
The multiplayer boss was somewhat of a letdown. Gilgamesh last week was a hard challenge that required a good team working together. This poison dragon boss was a pushover with easy to hit medal requirements and no real strategy required. Some random aoe's, some weak counterattacks, and... that's all he did. Oh well, they can't all be extreme difficulty I guess.
