Which is the same as Expanded Mags for reference. As it currently stands, only the Paragon and Scarab can effectively make use of this hullmod due to its extreme OP cost and drawbacks.
While this will make Paragons with HSA more powerful, it would only be a buff of about 10 OP which isn't sector ending.
Its current price point is equal to either of the two Flux hullmods, which it just isn't worth taking outside of the two above extremes. Decreasing that price point opens up more builds that use hardflux beam weapons either fully or as a mix alongside energy bolt weapons. Likewise, it would function as an indirect buff to certain beam PD such as the PD and Burst PD Laser. ExMags is better for BPD, however if a built doesn't need it outside of PD, and the build can integrate one or more offensive beam weapon, then HSA would work as a nice alternative.
If that still somehow ends up being too expensive (mainly for frigates and destroyers), dropping it down to 2/4/6/10, or equivalent to Advanced Turret Gyros, should be enough.
