i think the long & skinny of it is that beams doing soft flux is not as much of a big deal as they're made out to (aside from for triggering shield arc-thru), and thus are not worth losing half your range. The only ships who are put in any worse of a position vs a beam ship that does hard instead of soft flux are ships with way higher flux dissipation than their weapons can use, which is... what, a hound with a vulcan on one of its 2 slots? Basically any ship that HSA gives you an edge over is necessarily so little of a threat as to be not worth building against. The only use-case for HSA is if you want to mix beam weapons into a non-beam loadout without the beams messing the AI up. For example; I build an Odyssey using HIL & Tachyon(for emp) on one side with all its small slots on that side loaded with antimatter blasters, a triple autocannon on the front, 2 sabot pods & a large HE missile (didnt matter which), and nothing on the right or back. I put HSA on it so the lasers would have the same range as the AMB's. If HSA didn't give any benefit & just cost 1 OP I'd have still used it, and any build where I need the benefit that it does give, I just... use a different gun
edit: like, I'm trying to get this thought put together right; unless your enemy has way more dissipation than its guns use, beams already basically do do hard flux at half their range anyway. They only do freely dissipatable damage when ur outside of an enemy's range, (again assuming the enemy is a warship kitted with more guns than it has dissipation for (which it should)) once the enemy gets into range to attack you their flux is going to start going up from soft flux just the same as if they were taking hard flux damage. So HSA doesnt... do anything... The only thing it really Does, aside from line your beam ranges up with your non-beam ranges, is allows you to run an ion beam with a graviton or tactical beam setup, which is still not viable even with this hullmod. You could replace it with a free hullmod that just instructs AI to keep their beams weapongroups off until they got in range of their non-beam guns & it'd achieve the exact same thing
