We did an achievement run for Mythic Uldir in June of 2022, 9.2.5 of Shadowlands.
All bosses except the last can just be smashed out, no mechanics were really necessary. We did find on G’huun we had to actually do some work. We broke up into 5 groups (1 for tanks downstairs), and 2 left groups, 2 right groups, and really coordinated it for success. Click to 1:14:30 to skip to that successful fight so you can get a bit of a glimpse of what worked.
