Preferred Healer

5 x 540= 2700 vs. 7 x 360=2520. However, DRK also has an oGCD that is purely a mana cost in Dark Passenger. It adds 250 potency to DRKs spam potential without adding any time or GCDs bringing its total to 2770.

A few things you left out:
The added dmg bonus from CS and DS
Aero III
WHM also has:
Assize and PoM which can be used without adding any time.
You also may need to consider Grit's dps penalty.


Lastly, how much dps the WHM or DRK job can do individually is secondary. It isn't so much a question of who has better dps, but:
Will party dps be higher if WHM delays Holy for 15 seconds b/c of BP, or if DRK hold off on BP for ~6 second stun... Typically, its the latter.
