You know, maybe I was too harsh on these cuttlefish guys on my first read. I didn't notice they punched quite as hard as they did, 12 of them are a very durable, surprisingly killy character guard squad for 120pts, even if they do turn off when their boss dies so they're vulnerable to snipers.
If Mech weren't essentially forced to take Retinues only with Logistical Benefit due to bad detachment count I'd consider squads of these with a cheap Cybernetica Tech-Priest in as bulky scoring. As is, spending both Prime slots on a Paragon Arcuitor + 12 cuttlefish for her to stand with is sub-300pts for a Siggy-tier duelist and enough beef to hold off your average Praetor + 5 elite Termie squad or pack of choppy vets trying to get into your deployment zone.
I feel like every other mech unit I look at would be a really fun pick if they had slightly better detachments/weren't screwed out of transports by faction keyword incompatibility/could bring a HQ that kept up with them, I'd like to put that squad in a Macrocarid but the Macrocarid can only transport Macrotek, and I'd like to have the Arcuitor up the board a bit but there's nothing else with Infiltrate..
