Fair points, thank you.
Reason why there aren't more bodies is due to keeping the list at 50 Power too. I had to sacrifice a 2nd Dunecrawler to fit another Vanguard squad in, though also I got another Dragoon in.
I'm really feeling the Skitarii are a tax and the Spearhead with 2 Dunecrawlers felt more mechanised and able to wipe heavier lists... However the Battallion does feel more of a manouverable list-build.
The main concern is putting more bodies in the Skitarii squads steals points/4 Power from something else and they have an Ld 7 (with a reroll from enhanced data-tether) with their Alpha... I'm just very worried they have T3 with 4+/6++ and will bug out to losses.
Potentially I could divert the melee weapon points to redirect to the Magos and give him an eradicator ray. Even though it's d3 shots and I tend to roll low, whilst volkite is a flat 3 (though no rend is potentially an issue).
With points drops and still few options, I'll have to go more Spearhead-style to fit 1k points into a 50 Power List.
I still also think that the Datasmith, whilst only able to heal Kastelans, at 2+/5++ and armed with a Gamma Pistol is just better than an Enginseer, though having the extra Command Points for a Battallion is super helpful.
I have both lists saved and see what point drops could do.
