Only Bombers get a bonus against H/Ks.
I started a thread about that little quirk a while ago, and Keith pointed out that in fact Zenith Polarizers, Impulse Reaction Emitters, and Youngling Vultures also get bonuses agains H/Ks.
Polarizers, IREs, and Vultures don't get a bonus, they just don't do poorly.
A single Mk I Bomber does about 4,900 DPS against an H/K.
A Mk I Vulture does 600-5,600 (% based) DPS.
A Mk I Polarizer does about 6,000 DPS.
A Mk I IRE is the best, doing 9,000 DPS.
Per Cap, they're all good (better than almost all other ship types) but so are Blade Spawners, for example (250,000+ cap DPS).
Acutally, the BEST unit is the Spirecraft Implosion Artillery: a single Mk I does a whopping 250,000 damage per second vs a Mk I H/K.
Always forget about that one.
Using Spirecraft Rams on starships is a waste - something you'd only do in a final "I don't wanna die!" emeergency situation, I hope.
Reptite is abundant and Rams are dirt cheap. I often use Rams against powerful Starships in exowaves, etc.
Hmm. I always reserve my Rams for Golems, since I always seem to find more stuff to build (or re-build) from even low level asteroids than there are asteroids available. Do you skip Implosion Artillery, Siege Towers, and Shield Bearers?
