I'm actually relatively fine with IRPLs, after considering I use them everywhere; however, I only really use them because the only other hard flux energy weapon option for small slots that is not an AM blaster is the Ion Cannon... I'd like some weapon variety here, or maybe even give beams a 25% hard flux damage.
This is why I post that small energy weapons are generally bad except as PD (anti-missile, anti-fighter, anti-low tech frigate). I pick light ballistics over all of them, except maybe some beams for anti-fighter.
I would like beams to deal hard-flux, but the AI does not know how to deal with continuous damage sources (beams, shield ramming, etc.) With the recent range extensions to most beams, beams dealing hard flux would make kiting for many ships too easy.
Since Ion Cannon did not get any damage boost to compensate no flux supercharge, it is worthless at killing things, good only for shorting out unprotected targets.
For AM Blaster, that should not be so expensive. It is only good because of AI's... predictable flux management. AM Blaster also has a lot of fade (presumably to make up for 400 range), which the AI is unaware of. Also, ammo. It should lose the ammo or some OP cost.
