Well blades of khorne and stormcast don't really count... they realised they forgot the traits and things they were prepping for ghb17 so smashed everything together, not really a new release,
So just Tzeentch and karadon overlords really, and they were very close together.
So thats 2 armies. For The year.... There's been alot of empty weeks I've noticed tbh, alot of boxed games, 2? Months of 40k and feels like 8 weeks of deathguard...
2018 needs to be better
