LF are useless right now, because they can be easily killed by a skilled VHF/HF fighter. Hell, they can be take down by literally everything with little skill and luck.
If it was for me, I'd make something that I came across on the Paralyzer's infocard, as they are said to drain energy of the ship (not sure about it though).
So:
Why not to make LF-only gun or missiles that would drain your energy violently?
This way, LF would be pretty useful in disabling ships and e.g LPI would finally make use of their symbolic Liberators.
