As a healer, I am mostly standing still, and when I do it with my FC I'm always #1 so I am also de-fearing and breaking chains most of the time but I have still little do to lol. As far as mechanics go I think it's pretty easy, but it requires a lot of communication and that's the hardest part. The dps check is quite tight too compared to the other primals as well. It's one of those fights were voice chat helps a lot.
