I can't vouch for Machinist yet, but I'd like to remind a few that it shouldn't be compared to a melee job like Ninja or Dragoon. As a melee (and DRG being more or less pure damage), they're entitled to have higher potentcies on their attacks.They aren't categorized as "support DPS" and being melee forces them to disengage the enemies more often than a ranged job.
