Yeah, I think that's quite cool. I remember reading that Dregs have their lower arms cut off to show their low class, which is also interesting. I'm guessing that "servitor" hints at that robot status.
Yeah. The Cabal music is good tho.
Those ancient structures look Vex too, which is kind of neat. I get that Mars is the desert planet, but it feels really barren in a bad way. And, yeah, the Cabal just aren't that interesting. The Phalanxes are OK, I guess, but the rest is just lumbering headshot sponges.
I wonder if there'll be a Fallen raid and then a Cabal raid.
