4th job Single Target DPS

We don't have a casting time for that, first of all.

Edit: For anyone interested, I made a quick and dirty mobbing DPS comparison:

Blizzard = 41032 x 15 / sec
Meteo = 40043 x 15 / sec
Genesis = 32938 x 15 / sec
Battleship Torpedo = 57271 x 6 / sec
Fury = 54885 x 6 / sec (27443 without Berserk)
Advanced Charged Blow = 46290 x 6 / sec
Fire Demon + Elquines = 50978 x 4 / sec, or 46102 x 6 / sec
Brandish = 89279 x 3 / sec
Crusher = 84823 x 3 / sec (42412 without Berserk)
Ice Demon + Ifrit = 45264 x 4 / sec, or 40263 x 6 / sec
Flamethrower + Ice Splitter + Amp = 37077 x 6 / sec
Snatch + Shockwave = 32520 x 6 / sec
Pierce (pre-KMST) = 29443 x 6 / sec
Boomerang Step + 2x Band of Thieves = 38195 x 4 / sec, or 29229 x 6 / sec
Dragon Strike + Energy Blast = 29972 x 4 / sec, or 26533 x 6 / sec
Avenger + Shadow Partner = 26227 x 6 / sec
Arrow Rain/Eruption = 24161 x 6 / sec
Inferno = 23334 x 6 / sec
Shining Ray + Bahamut = 22545 x 4 / sec, or 19880 x 6 / sec

Obviously there are issues with using DPS to compare training effectiveness, especially when mobbing comes into play. But this basically tells you how much damage you could expect to do to 15 stationary snails in front of you, with 2 bil HP each...
