All of their abilities involved in keeping their dps mechanics active are instant. They do not suffer from the immense frustration I described in my original post, which is pressing the button in time and being denied the reapplication of Enochian.
Additionally, and I would appreciate it if an expert Dragoon could clarify this for me, but if a dragoon screws up their Fang and Claw or Wheeling Thrust application, can they not just simply start their combo chain over with the other one? Also, can't they simply fire off Fang and Claw or Wheeling Thrust every 2.5 seconds once they have sharper or enhanced wheeling up, or at the very least on demand?
Black Mages have to go through an intricate juggling process of several effects, all of which involve lengthy cast times, get no second chances, and absolutely cannot refresh Enochian during their "damage" rotation, only at a specific part of the mana regen phase of it. Unless I misunderstand several somethings about the combo chains and the buff effects they grand with Blood of the Dragon up, the two classes really aren't at all comparable in terms of difficult and punishment.
