according to my calculations, it would take 31 harpoons to kill a standard (no additional armor or armor related skills) dominator, and 60 to kill an onslaught....
60
even a weapon that is supposed to do significant alpha damage vs armor is pretty ineffectual... and this is if every single harpoon hit on the same location. In reality onslaughts have shields and a lot of point defense.
a couple more weapons for reference vs an onslaught:
570 heavy mauler shots (4.75 minutes for two heavy maulers to kill onslaught)
8 reapers
60 hellbore shots (meaning a dominator with two hellbores firing into an onslaught would take 1.5 minutes to kill it and thats only firing into hull/armor, not even counting time shooting shields)
118 heavy blaster shots (thats 85000 flux worth, more than 3x the paragons flux capacity, and still over a minute of continuous firing for two heavy blasters)
41 plasma cannon shots (61500 flux, and I think 55 seconds, not sure if I did the time calculation correctly)
and then weapons that aren't high alpha damage
pulse laser 2075 shots that means a medusa or aurora with two pulse lasers would take 5+ minutes to kill an onslaught just firing into hull/armor... 1028 shots to kill a dominator is 2.85 minutes for 2 pulse lasers and 14080 flux
970 autopulse laser shots, meaning firing only at the burst rate of fire, it would take 45 seconds of continuously firing into an onslaught to kill it... this is a large energy weapon... and the ammo regeneration rate is 2 per second, so effectively 970/2/60=8.03 minutes roughly firing every shot as it regenerates.............
every weapon I listed above is a medium or large weapon. These are supposed to be at least moderately effective against large ships, but they are borderline useless. Don't even think about kinetics vs hull...
this just doesn't make any sense balance wise. high armor ships are virtually un-killable using normal weapons
this also throws off the tech balance, consider aurora vs dominator. A dominator with two hellbores takes 27 seconds to kill the aurora but the aurora with three pulse lasers takes 1.9 minutes... and the dominator can still equip 3 medium missile pods and two medium kinetics as well as small weapons, the aurora can get a couple small missiles and a couple small energy weapons.
edit: harpoons are just trash, dominator can tank 20 in the current game and onslaught 30, but still doubling the number is pretty bad
it seems like compared to vanilla
missile generally need 2x hits for large ships, more on par with vanilla for small ships
most high explosive weapons needed 3x hits
medium and some large energy needed 4x or more hits
kinetics and small energy were like 100s of times more hits, for reference, ir pulse laser need 300000 hits to kill dominator. yes three hundred thousand
I think maybe if these ttks were brought more into line with vanilla, the concept of needing big weapons to damage big ships is interesting. The ttks are just a bit ridiculous and the energy weapon balance is definitely off, they are already underpowered. The balance is also significantly better amongst smaller ships, its just when you start getting into high armor ships that things get crazy.
