Ah. I think I'd prefer the longer ranges, honestly.
Same here, so I went for the modified ranges. Since I will probably not be able to relist already existing weapons, any that do not appear in my update can be determined by using the following formula: drop extreme range (not used in MW2) then divided all ranges by five (rounded up). Minimum short range is 1-2/x-x/x-x. IF Med/Long range are les then 15 then weapon would be 1-2/NA/NA.
Number 2, which ties in with...
I do not. Sounds like something to hunt down.
