While you were writing that post, I completely changed my answer. You're actually better off with Scarabs or Flayed Ones. Praetorians take the place of Terminators, and you shouldn't be spamming those.
Yes they do (in fact they have two!) and I can already tell you that they're awesome.
ION; So GW just introduced LOYALIST Marines with skull-face masks because Massive Edgelords only play Dark Eldar or Night Lords, and not Space Marines. So now if I get some, I have to paint them black and field them alongside Sisters of Silence with pink and/or blue hair (The M'Ladies). Also, I'll model their swords into Katanas, and the one that isn't in a helmet obviously has to wear a fedora. They might just be the dumbest models I've seen in a while, and I don't say that a lot about GW miniatures.
