I'm not sure about some of those changes. LRFs should still hit LFs badly in my opinion.
However, LRFs should have their effectiveness highly reduced against other types of ships.
The problem with LRFs rite now is that they work good against everything, as long as they're protected from fighters. Structures, LFs, Caps, support Cruisers, carriers; you name it - they blow it. Only HCs take a moment to destroy, but it is still way easier to amass LRFs in an amount to wipe a HC fleet than the other way around.
1. LRF should be made a specific counter to structures and LFs, not a massive damage dealer against everything as they are now.
2. LFs should receive some boost to their usefulness (reduced supply cost a bit, slightly buffed damage against capitals and HCs) so they really are really needed in late game and so that they would need a counter.
So basically... yeah.
I only oppose that LFs should get a buff against LRFs and that LFs should deal as much as LRFs do against heavy units now. LRFs should get nerfed instead, otherwise all caps and HC will get blown away as soon as they appear in the gravwell.
