Freeblades and Dreadblades

Have a single big Knight that you always wanted to bring with your army, but you don't because you're afraid he'll break the mono-faction bonus (like Combat Doctrines or Cabalistic Rituals or Martial Ka'tah)? Well, fear no more! Warhammer Community has confirmed that Freeblades and Dreadblades now count as Agents of the Imperium/Agents of Chaos, so you can take them without breaking your mono-faction bonus!

Why did they mention Adeptus Mechanicus's Canticles of the Omnissiah as an example when we already have Knight of the Cog? Uh, I suppose it's to alllow Adeptus Mechanicus to take an Imperialis Knight without breaking Canticles or Imperative Doctrina instead of being forced to a Mechanicus Knight? I honestly don't know. But why would you do that when you lose the Mechanicus keyword and therefore the refund of 2 Command Points when taking a super-heavy auxiliary detachment as opposed to spending just 1 Command Point on a single Mechanicus Knight? Hmm?

Oh, another interesting bit. Apparently Armigers are Objective Secured in an all-Knights Detachment. What the f does that even mean? Aren't...all detachments locked to a single faction? It's not like you can take Knights and other faction's units (Lords of War) in the same detachment - firstly, they need to share a keyword that's not Imperium or Chaos, secondly, I don't think there's many Lords of War you can take unless you're somehow souping Knights and Baneblades in the same detachment.

On the other hand, if you decide to take a Freeblade/Dreadblade unit of 3 Armigers/War Dogs, you can! Not only will you have essentially 3 small Knights running around with your armies without breaking mono-faction bonuses, they get Objective Secured too. So you don't need a pure Knight army to get Objective Secured Armigers anymore. Yay.
