They wouldn’t. T2 spec skills only apply to T2 mods. In this case, T2 mods get a ROF bonus. Faction mods may be able to fire T2 ammo, but they do not get the T2 spec skill bonus to ROF.
Just tested in Pyfa, and it seems even if you have Spec 1-2, you’ll end up doing more damage than the Factions. Which is lame, b/c I know some of the other guns under-perform until you get Spec 4-5. Then the T2 mods finally pull ahead.
Sacrilege offers 5% bonus per level in HAC skill. Not counting HAM Spec skill, HAC 5 gives you…
Rep Fleet HAM = 3.56sec
T2 HAM = 3.67sec
HAM Spec offers an additional 2% bonus per level to the T2 mods, but not to the Faction mods. Adding that in…
Rep Fleet HAM = 3.56sec (still)
T2 HAM = 3.3sec
Now you can massage those numbers around however you like. But chances are you’re probably flying the Sac with a reasonable amount in both HAC and HAM Spec. In which case, it looks like the extra 2% is enough to make up the inherent difference in the Mods themselves.
I made the maths a while ago and the duration to empty the clip is almost 100% the same when comparing caldari and T2. (around ±1% difference)
so CN is just plainly better than T2, except for ammo consumption.
This. On a base Sac hull, no other mods than launchers, a full rack of CN launchers gets an extra 10dps (at all 5s with rage HAMs), 75 missiles loaded vs 66 (T2), which in pvp could mean the difference between living & being exploded.
You could do this and see the same dps as the CN launchers, you’d also have slightly more CPU free, and a bit less pwr grid free… and a lot less isk… unless you’ve got a bunch sitting around somewhere.
Hmm… I know… But the Sacrilege is a Khanid boat and it would fit sooo well, and even more if you would fit Khanid ballistic controls, Khanid Navy scram and web…sob…
Fitting is also very important, T2 can consume up to 20% more cpu/pg than faction and meta equivalents. It can be the difference between fitting a t2 scram or undocking on a compact one.
