Deep One villages don't have a hard purpose if you already have Aquatoids. But these villages still exist and are available for raiding, if you like it or need points.
I don't think they have any advantage compared to a city.
In-universe raiding villages also makes little sense after this point. X-COM ignores individual sightings and small outposts for cults and Cyberweb, why should Deep Ones be treated differently? (It's not a rhetorical question
)
Unrelated: I shot down Cyberdreadnought, captured it in Dimension X, finished all related researches, finished the arc by mid-month, and next week I got attacked by it again.
I understand this is an engine limitation. But can there be an in-game explanation for this ship appearing again? Cyberweb experimenting with time travel? A research item that only appears after the Cyberdreadnought capture would give a warning that according to its logs it had jumped to undetermined dates in the future and back, and give a warning that this ship may appear above Earth again. Something like that.
