Some comparative thoughts on Warthog options (sorted by cost), now that we have Dorsal Turret revealed:
Twin Laser Turret (6)
Range 3 utility.
Primary weapon "pea-shooter" attack can help strip defensive tokens prior to TLT shots.
Anti-synergy with the Y-wing's 2-dice primary, since it has a Range 1 donut hole.
Full modifiers on 3 attack sequences are basically impossible to come by.
Tops out at 4 potential damage when activating at Range 2-3.
Ion Cannon Turret (5)
No benefit for Range 3 shots.
Tops out at 3-4 potential damage depending on Range.
Focus and TL assists from squadmates or upgrades can allow full modifiers on both attacks.
Extra benefit of ionization.
Blaster Turret (4)
No benefit for Range 3 shots.
Tops out at 5-6 potential damage depending on Range.
Nearly impossible to have Focus modifiers on both attacks.
Dorsal Turret (3)
No benefit for Range 3 shots.
Tops out at 4 or 6 potential damage depending on Range.
Focus and TL assists from squadmates or upgrades can allow full modifiers on both attacks.
Autoblaster Turret (2)
No benefit for Range 2-3 shots.
Tops out at 5 potential damage at Range 1.
Focus and TL assists from squadmates or upgrades can allow full modifiers on both attacks.
I think between Dorsal and Blaster turrets, the Dorsal clearly wins. It's a point cheaper, allows a modified attack with an available Focus token, and the sacrifice of the 3rd attack die at Range 2 seems an acceptable tradeoff.
Now, as to how the Dorsal turret compares to the other options, I think it's more a case of what you plan to do with your Warthog in the context of the rest of your squad. But even against TLT, I think Dorsal wins on cost, modifiers and the jump in potential damage at Range 1.
Thoughts? Now I just need to learn how to reliably fly the things.
