The ravenous shadow mission wins.
Am I missing something here? Like is this one ofthose missions where you either optimally deal with it or lose?
I am pretty sure we applied dps as efficiently as we could, with the unlocks we had (mostly hbc). What else are we supposed to do? Cry ourselves to sleep because we failed a gear check?
I find the gear check for this one to be brutal. I've done it once with a spire destroyer equiped with impulse emitters and plasma sieges, and the second time with a powerful Z destroyer with impulse emitters.
Both times I did not stop the devourer until it had crushed the supply of enclaves.
Gear matters, a LOT, in this scenario. Although it can be done with general modules, what you really want is Missiles for your heavy modules and Armor Polarizers for your lights. On top of that, I find it best to not bother trying to save the Neinzul, don't even bother trying to save the small starbases. Just chase the Shadow around until it starts in on the Large starbase, then use your shields to try to protect it (and the Allied starships). Even then, you might fail.
Numbers:
Mk I Missiles do 150,000 DPS against the RS, Plasma Sieges do 100,000. HBCs do about 75,000. Bombers would be a good choice, if they didn't get killed, but they are insufficient decoys to protect much, either.
Mk I Polarizers do 55,000 DPS, IREs do 30,000, all other light modules do no better than 17,000 DPS. Doom Accelerators may seem good, but they cap out at 46,800 DPS.
