Thoughts on SLAMs for SG2 [SG2]

SLAM:
Come in size 3-5.
Fired direct fire, but with a kind of special resolution. I initially looked
at Arty resolution, but figured with a DF weapon that the rolling vs.
leadership made little sense. So....

Designate a target point. Roll Crew Quality Die vs. Raw Range Die. No terrain
or other effects. (Except blocked LOS of course!) Raw Range die is
0-12" d4
12"-24" d6
24"-36" d8
36"-48" d10
48"=60" d12 If Crew Quality Die > Raw Range Die, impact on target point. If
Crew Quality Die =< Raw Range Die, impact deviates. Direction D12 Distance is
1 roll of Raw Range Die. (Further away you are, the further you are likely to
deviate).
Impact is as artillery (GPE, Anti-Armour, Anti-Personnel depending on
weapons load out). Beaten zone is (Size Class)" x (2 times Size Class)". That
is, a
SLAM/3 has a beaten zone 3x6, and a SLAM/5 has a beaten zone 5x10.
I think this is fair, given that under this system the Impact is a constant.
Just the area is bigger (more rockets saturating a wider area).

Thoughts?
