In your list entry, there's no jump packs on the assault squad so that's why I assumed that they were for the SR. I would still suggest that proxy them as footslogging
DC, then you can put more of them in the SR, Mephiston is walking as well. I'd drop the sanguinary guard with Dante and
JP DC with Lemmy inside cover for better change of beta assault. Even with Lemmy's re-roll it happens too rarely.
I see your point in placing Dante and
SG in the SR, but if you think how big point sink it is for you "all the eggs in one basket". Don't think your SR will last until the end of T2.
SR is good for tranporting hammernators and I'd recommend squeezing a dreadnought in there. Even that
BA has the fastest dreads, still SR is the only closely competitive method bringing your fragiosos/
DC dreads in range. I tend to use a librarian dreadnought with the SR to give buffs. There's actually one my made batrep with libby dread and 6man van vets in a SR, if you scroll a page or two.
In my meta we use the upcoming chapter aproved sneak peak for the +1 to who starts (same as ITC). Also power fists are 8p less in points vs. the index. That's widely used rule that
DA&
BA and other non-codex chapters can use the updated points from the
SM codex. Biggest changes are the
PF and predator pricing.
So my suggestions are:
play the assault squad as a footslogging
DC with boltguns and chainswords accompanying Mephiston for buffs.
Drop Mephy and the assault squad and squeeze a hammernators and a dread (libby/furioso/dc) in the SR aswell.
DS Dante with the
SG, if you are feeling lucky, you can drop them to drop a minor armored threat with overcharging
I use Dante and plasma
SG for such play, but they are accompanied with 2x 3man squads of plasma company vets with jump packs with one storm shield.
If your not into proxying, I think it took like less than 30min for me to cut all the wrists of my bolt pistol
DC and glue a boltgun ~20 models. I just sprayed the boltguns beforehand and threw some nuln oil after glueing. tabletop! I recommend using super glue, so most times plastic pieces just snap off if you really want for easier "swapping", you never know what the next edition brings. (drop pods viable again, hehe)
Btw, I suggest using a single plasma cannon/
dev squad. Now that you can target each weapon at each target some heavy weapon saturation is solid. With the signum from the sergeant you can't ever explode your plasma cannon. You don't even need a captain to baby sit for those re-rolls. Something to look up, something I've learned by doing.
rapid fire from the boltguns before an assault is
imho a better option than the bolt pistol shooting in the close combat.
Hope this feedback from a single source has any help for you. Too rarely we see
BA lists in here after all!
