First off, Thank you for your advice, I'll be taking it about the pistol and techmarine. I'd like to apologize about how this next part sounds, as I'm going to tear everything else apart. I really don't mean any offence, I just like to mathhammer
Plas vs Grav:
For infantry
plas is going to cause 6 wounds per 10 shots (10 x (2/3) x (5/6)) against everything up to T6. If the squad doesn't move or has S&P grav will cause 8 against
TEQ, 6 against
MEQ and 4 or less against everything else (eldar, tau,
IG, nec, ork, ect)
plas is also insta death against anything t3 or less (eldar, tau,
IG ect) while grav has no S value and a shorter range.
Grav's only really better against terminators. If you move your men, it doesn't even have that.
For vehicles: Grav is only better at
av 13 or greater. Yes, you cause double wounds after the first, but you only wound on a 6, while for all armor under av13
plas will wound twice as much or more (at
av 12
plas kills on a 5 or 6 negating grav's extra wound) Positioning helps for
plas here because you can often turn that 5,6 into a 3+ by shooting at another side of the tank.
Grav's only really better against Land raiders.
" +1 T is comparable defensively to rerolling ones(WAY better against S8-S9)"
Well... no, Not in any situation.
increasing your t by 1 gives you a 17% increase in survivability against S1-S6 wounds, grants
fnp against 8,9 and does nothing at 10 or D. for S7-D they're still killing you on a 2+ most of which is ap2. So against a S1-9 shot with
AP you'd have your invuln 3++ and
FNP 4++ You'd loose 1 in 12 wounds. S10 would net you saving 2 in 3 wounds, same with D.
This is a re roll-able 2++ so no matter what you get hit with you come to the table saving 35/36 wounds. with your same 4+
FNP (admittedly only S1-S7) you save 71/72 wounds. Gorgan's chain turns that into 143/144 wounds. There's just no way a t5 can is better than 2++
rr. Since both captians have
EW the only thing they fear is a
SD shot that rolls a 6 and removes them from play. T10 Won't save you from that though.
Positioning is a major list weakness but not as much as it might be because most of the missions are objective. As long as the unkillable guy is still there I'm at least contesting.
