Rokh Versus Raven

I've been running missions with a corpmate (from now on known as Grey) and he flies a Raven. I decided to look at, based on my skills, which battleship is better for running missions.

Rokh - Passive Tanking
Lows:
3 x Magnetic Field Stabilizer II
2 x Power Diagnostic System II

Mids:
Tracking Computer II
Invulnerability Field II
Heat Dissipation Amplifier II
3 x Large Shield Extender II

Highs:
8 x 350mm Prototype I Gauss Gun

Rigs:
Capacitor Control Circuit I
Semiconductor Memory Cell I
Anti-EM Screen Reinforcer I

Drones:
5 x Vespa IIs

Raven - Passive Tanking
Lows:
3 x Ballistic Control System II
2 x Power Diagnostic System II

Mids:
3 x Large Shield Extender II
2 x Invulnerability Field II
Heat Dissipation Amplifier II

Highs:
6 x 'Arbalest' Cruise Launcher I
2 x [empty high slot]

Rigs:
Anti-EM Screen Reinforcer I
Warhead Flare Catalyst I
Warhead Calefaction Catalyst I

Drones:
2 x Wasp Is
2 x Vespa IIs
1 x Hornet II

According to EFT, with drones factored in the Rokh has a volley of 1565 and DPS of 479 while the Raven vollies 2852 and DPS of 454. For defense their shields are 21664 and 20342 respectively and resistances are about 1-2% higher for the Raven.

I was a little surprised the Rokh outdamaged the Raven but then factor in the ability to switch damage types and the Raven is a lot more attractive. Also, my missile skills are merely adequate so let's see how the numbers change if my skills are bumped up: just putting several skills to level 4 from level 3 (especially Warhead Upgrades and Cruise Missiles) jumped my volley to 3032 and DPS up to 474.

So yes, the Raven is a better mission running when the changing of damage types and non-issue of tracking is factored in, even for me and my uber gunnery skills.

The next question is, what about torpedoes? Replacing the 6 cruiser launchers with 6 siege launchers gave a volley of 4277 and a DPS of 569! With my level 3 missile skills. WOW! I can see why CCP are cutting their range down in Trinity because that is damn impressive.
