It seems that the forum opinion on this weapon is that its somewhat underwhelming, yes it lacks the Awesome pressure of the autopulse, and the map-spanning range of the (pre-nerf) tach lance But it is supposed to be a mid-long range support weapon. Its cheap OP wise for its size class, and very flux efficient, being a gav beam on steroids, it fills the role nicely... except... It turns so slowly....
Too slowly, in my opinion, for a weapon that is designed to keep constant pressure on enemy craft to reduce their venting capabilities, force them to keep shields up, and thereby speed up the overload from assault/strike craft or reduce the volume of incoming fire from an enemy craft. However, this is difficult to achieve on anything more maneuverable than a capital ship due to the terrible turning rate of the weapon, Its nearly impossible to keep a frigate under sustained fire and god help you if you want to hit fighters with it... (Yes I know, its a large slot weapon, but beams are supposed to be the jack of all trades weapon, right?)
TL;DR, The HIL could use an upgrade to its turning rate to make it a much more useful and viable support weapon, increasing its effective DPS without changing its actual DPS stats.
What do the rest of you think?
