@AndrewChristlieb Hey man, its just a game. I can't speak for everyone else here, but were trying to improve the overall experience of BFG. Like with allowing the NC on the tyrant, which I do not support, it's impossible to make everyone happy, so we have to make compromises to enhance the overall experience. If you are very strongly opposed to the current NC discussion, throw out the closest NC rule system to the proposed one that you are willing to accept, and like me (I love NC very, very much) you will get some say, but have to compromise somewhat.
As for different ammo types, it is interesting but it seems most BFG players prefer the game as simple as possible; in some instances I think people almost want a game of checkers over an actual miniature game, but I digress.
I think d2+2 would be fine, with d2 for splash damage and our LO and new range bands, with restrictions. Its more accurate against capitals (if SO intensive) if less explosive while being less damaging but much more disruptive to escorts (clumped up escorts are fair game, scattered ones are low profile). Not too much different than torpedoes in that sense: easier to hit a large base, but likely to inflict less damage. Smaller bases are harder to hit, but if they are grouped up too closely you'll throw the whole squadron into disarray. And this keep the benefit of the direct hit tangible; more damage but not overwhelmingly so.
