With an aggressive officer, that same build would be better without HSA, because it can hover in/out of midrange to use ballistics, and also provide constant long range support. With HSA, your beam range is cut to 600su, and given they're toward the rear of the ship, is noticeably shorter than even the 700su ballistics. This forces the Eagle to try to stay at <600su, which drastically cuts down on it's survivability. The only gain you get is ~700 hard flux on shield, bad trade imo.
I mean, in terms of a midrange skirmisher, this is worse than a 3x kinetics + phase beams build both in terms of burst and range, because you don't get adv optics.
