Thank you for the inputs.
@magenb: At this time I will not be accounting for flesh/armourbane, nor instant death except for the double S. I intend to apply it later though, where if the medium, and median toughness would be T4 the fleshbane rule would be priced as S6 without instant death or something similar.
Yes move(M) is something I will try to account for at the same time as range, so if you have an assault marine, their CC weapons will be considered to have 6" extra range when pricing them.
The S8 AP2 weapons will be priced accordingly.
Having extreme characteristics or stats like T10 Sv- or T0 Sv2+ would of course be more expensive just like S10 AP- and S1 AP1 weapons. But that is later consideration after the characteristics are set those thing will easier fall into place.
@Wyddr: I think the ID and D weapons should be priced rather that getting a discount on multiple wounds, however each additional wound will probably cost slightly less. So increasing from 8 to 9 wounds would cost less than increasing from 1 to 2 wounds, in general, but of course also modified by the T and Sv values.
I still think T +1 should cost less than W+1, but I will take it into consideration.
You might be right with S and A being equally valuable, I'm thinking 5S5 hits would be most valuable, followed by 4S6 and 6S4, but then S6 has a higher chance of causing multiple wound by instand death, so the even values of S should cost more than the odd ones.
@Every1: I'm thinking I will have to use 2 set profiles with set points to be able to start a point cost curves for every stat, my suggestion is:
WS0 BS0 S0 T0 W1 I0 A0 Ld0 Sv- cost: 1 point. (no gear)
And
WS3 BS3 S3 T3 W1 I3 A1 Ld7 Sv4+ cost: 5 points. (with a laspistol)
So if all stats were equally valuable, they would cost 4/26 (0.15) points for each +1 in any stat, but that's not reasonable. Each stat would have to increase or decrease exponentially, with crotch values like when BS goes above BS5 the curve will have to change.
I'm thinking for each point in S you get a free pistol with the same S, hence the laspistol as default, also for each extra A your "pistol" get one extra shot as default value.
Is that fair?
