Once I posted a table showing different point values for different weapons. Here it is again, with Uncle Joe's latest proposal on it. (UJ, have I got it right?) The table formats well on the forum--not sure how many people will see it in the email list.
Uncle Joe pointed out that you should also consider the price of N actual weapon mounts. So compare one ROF 3 weapon with three ROF 1 weapons, for example.
Note that the differences in points are bigger than they look, since this still has to be multiplied for other weapon values.
a: (R+1)PD current rule
b: RPD + R
c: RPD (doesn't emphasize ROF, just for comparison)
d: R(P+.5)(D+.5) Uncle Joes's first proposal
e: 1.2(RPD + (3R + P + D)/5) Uncle Joe's current proposal
R P D a b c d e
