I'm not sure about that unless ranged is its own separate entity. We take 4RNG and DRG MNK SAM, and the 4 RNG account for 75%~ of the damage, DRG (still piercing) around 12% and SAM and MNK cover the remainder (they say they hate this fight because it makes them feel bad lol)
I'll put up a damage graph when I get home of our run yesterday. Our fastest yet, 5NM+bee in about 38 minutes IIRC.
