I would like to summon @SeaFalcon here, as he is the one who greatly impressed my back in 2010 with his LF fighting and who made me into LFs all since then and up to this day.
IMO, LFs are great ships. Yes, they eat mines, yes pro-fighters can still outturn you, but nevertheless those ships are great at surviving. Especially in mass fights. They are one of the ships that let you dodge incoming fire when dogfighting. I don't really know how do they behave with mines+CD or torps or missiles, because usually and mostly I go for guns-only.
I have survived @Silver in a Hussar back in 2012! I have survived and returned home on my own in a failed Corsair raid to Leeds, when we were crushed by battle Cydesdales...
I would like to say that making them distinct to some role is not really a good way to do it. They should remain in the fighters family, there is no need in making unique weapons, gear, etc. This won't balance them.
