4th job Single Target DPS

I don't know how you did the Dual Blade calculations, so I guess I'll give out a few points. As far as I can tell, the speed and delay of Chains of Hell (there's a delay after a successful CoH attack, before you can cast dark sight again) hasn't changed post-BB. Fatal blow has been nerfed to a level in which it's obsolete, so DBs either use Dark Sight + CoH + Upper Stab + Upper Stab, or just Upper Stab. Mirror Image works differently in that it's now a multiplier of your skill damage, but it still can't critical and it isn't affected by Final Cut (including its passive effect). Final Cut basically doubles your damage (same as pre-BB).

I don't know if you incorporated Pirate's Revenge, but it would be useful as an option to turn on/off.

Alright, I'll try to do the DB calculations again later. Pirate's Revenge is currently calculated as activating every 55 seconds. It's on pretty much all the time whether you like it or not :/ don't see a reason to make a checkbox for it.
