If the current convention is 1 deck crew per fighter, I don't see anything wrong with making the proposed corrections. that seems reasonable to me.
Correcting fighter loadouts to the 2/3 rule is fine, but the casual carriers creat a bit of a problem and I'd be with TarMinytaur in terms of just leaving their conversions alone. Perhaps adjust the deck crews where applicable.
I have zero problems with the proposed hardpoint splitting.
As far as the LYAs go...well, this is a matter of taste. Since I play this game pretty much solely in the D2 arena, I'm going to side with Nomad on making ships' LYAs coincide with the release of a given refit. Nothing bugs me more that seeing Klingon B-refits clogging up the yards on a given server as late as 2277 or '78 (or even later). The K-refits come out around 2272 or '73. There should be no further B-refit production after that date. As I said..this is a matter of taste and certainly this game is played in other manners than D2. However, if we're talking shipyard production, I can't see any reason that B refits would continue to be produced even 1 year after the K-refit comes out. Sure..some may remain in service as 2nd or 3rd echelon forces...but damnit, I don't fly 3rd echelon! heheh...
Love the shiplist!
