So after looking at my codex today, I realized Sammael no longer has a rule that states that if he is in your army, all Ravenwing bikes become troop choices(I'm still new to 7th Edition. Last edition I played heavily was 5th, and assumed that rule was in the book still). So can you no longer take a pure Ravening army anymore? I noticed the same for Beliel and terminators.
Am I not seeing something? Or do I need to now buy some scouts? If so, F you GW...
Edit: There is a detachment option in the dex that is for a pure Ravening force. Can that be your main detachment even though it has no troops?
