The new Ultimate Raid, which this article is about, has been super fun to watch in the background while I've been at work. We're now on day 3 or 4 and the race for world first is still on, with a couple of teams now managing to reach phase 5 of the fight - that's basically 10 hours of practice a day for a group of 8 people, to learn and repeat and learn a single fight with multiple phases. Total fight will probably only be about 25 minutes long from start to finish, but it takes weeks or months of practise to reach that finish.
The level of complexity to these fights and the standard of play required is just mind-boggling. Add in some really incredible lore and story content and the FFXIV team have another banger.
