After the game, I think that there are a few things I’d change, but here’s a pic of the army I took.
The Bloodthirster is just a gun magnet and degrades too quickly even with the Armour of Scorn with a 6+ feel no pain. I’d take a Daemon Prince with wings and more Bloodletters or a different fast attack squad.
On that basis I’ve built some Furies and will try some of them, plus a few more to bulk out other units. Further post to follow.
