The following are rDPS at 99th percentile.

E9S (Cloud of Darkness)
BLM, SAM. SMN is the lowest of the non-rangers but not by much.

E10S (Shadowkeeper)
BLM and SMN at the top. SMN is the lowest of the non-rangers.

E11S (Fatebreaker)
BLM and NIN near the top. SMN and SAM near the bottom for non-rangers.

E12S-1
BLM and SAM at the top. SMN and NIN are the lowest of the non-rangers.

E12S-2
BLM at the top with SMN, SAM, MNK trailing. DRG at the bottom for non-rangers.

The kill time at the 99th percentile for each boss and each job's damage rotation idiosyncrasies combined with uptime/downtime determines the rDPS numbers. The variance between the DPS jobs are still not that much, although BLM is always on top. The potency nerf on Tri-disaster really hurt SMN from ever competing against BLM.

The problem with the rangers are how unfun they are to play. The passive job role party buff is the biggest reason to bring them. Unless you are required to use Troubadour in a fight, there is almost no reason to bring them. However that is conundrum of most ShB job changes. They are balanced but boring to play.
