From time to time I see people mention lazors and how difficult it is to maintain the capacitor on Amarr ships, and while I agree to some extent, I suspect due to the multitude of crystal types that people only ever consider Multifrequency, Radio and Scorch.
I have run some numbers to try and illustrate how effective some of the other ammo types are. This data assumes all skills V for consistency, and was obtained from an Apocalypse (no cap bonus, no damage bonus) with Megapulse II; the workhorse of all laser turrets. I imagine the M and S crystal efficiencies follow a similar pattern so I didn’t feel the need to do an exhaustive analysis.
tl;dr if your capacitor is dangerously low, you don’t have to turn off your guns and wait for regen, swap out to some imperial navy Standard and keep on the pressure. It’s a 34% damage decrease but a 45% reduction in capacitor draw.
Also a lot of ships can be cap stable with Gamma, with a lot less investment in skills and cap modules. Normal and navy Radio/Microwave are horrible with the only useful scenario being for characters without access to tech 2 turrets.
now go buy my navy ammo stockpile
