I feel that increasing the LF's damage modifiers vs... preety much everything according to the readme was the wrong way to buff them... If you make it so lrms are needed to kill lf, instead of being able to rely on HCs?
LF's were strengthened directly in 4 ways...
First, they are better against heavy armor...LF v heavy armor was not as strong of a counter as LRF v LF or flak v fighter...the problem is, heavy armor is on support and carriers, so unless LFs are a lot better than HCs against heavy armor, then there is really no point in building them since heavy armor type ships don't contribute that much firepower...conceptually, it would seem the anti-support abilities of LFs would offset this, but in practice it doesn't work out like that...
Second (and third) they are better against caps and structures...for TEC and Vasari, LFs are still weaker than LRFs against caps and structures, so even though they were improved, these areas are still weaknesses...
Fourth, they are better against HCs...however, LFs and LRFs are about the same against HCs now (and LRFs were actually weakened against HCs)...again, LFs are simply being put on par with LRFs...
So, while LFs were improved significantly, I'd add that LFs were by far the weakest unit in the original game and still are countered by any combination of LRFs and/or HCs...
but carriers at level 2 cost a fortune
and illuminators take more labs to acquire than both the other lrfs
This is true...however, carriers can kite and LRMs and Kanraks are slower and LRFs are weaker against heavy armor and fighters are better against LRFs...carriers with fighters are now a very strong counter to LRFs...with LFs more potent as well, an LF/fighter fleet v a LRF/flak fleet can be a very close fight where as previously the LFs/fighters wouldn't have stood a chance...
Also, with fighters being a much better counter against LRFs, TEC and Vasari are at a disadvantage since their carriers are level 3 techs...
Illuminators at lvl 3 are still an Advent handicap...but, the handicap isn't nearly as bad now...I'd also add that LRFs are weaker against caps while LFs are stronger...so, having only half of their damage being frontal (and therefore able to FF) is not nearly as much of a handicap...in addition, illuminators are faster than Kanraks and LRMs (a marginal but still noticeable advantage)...
I do agree that LRFs may in general be on the weak side...making them stronger against structures I think would be the best approach for now...
