They definitely do have the highest ST healing, I never said they didn't, but with no offensive utility to compete with Beorning or Minstrel, as such they still aren't taken becuase the nature of Remmo fights are all DPS races, and raw HPS is not an issue.
And to think that the framework of dps support is already built into the class. a simple buff to Flurry (+2 to 5%) and changing Fates stone to a +% damage buff (+15-20%) rather than its useless mastery would make things a lot closer.
