While I don’t agree with the way @Kurrilino expresses their frustration, technically they have every right to be frustrated. This whole StD/Darkoath getting mentions all over but never releasing has grown old, not to mention that releasing a Slaanesh BT with no mortals added to the frustration of Chaos mortals players/fans.
Also, let’s be honest. This Open Day was a bust. GW might have got rid of a few armies in need of BTs in one go, that’s true and it’s a good thing, but the whole thing offered us just two soup BTs and a whopping one new miniature reveal. Even the expected Underworlds S3 reveal was a few seconds of two model silhouettes.
Seriously all that could be covered in one Community article, without the whole show.
