Beastmen are the folk horror army and that sub genre is in vogue in pop culture now as lovecraftian horror has become fully burned out and funkoised. Its like how Tomb Kings saw an uptick in 99' when The Mummy came out or Lizardmen in AoS when Jurassic Work released.

Personally i think GW should lean into it a bit more. Focus on the Gavebeast angle that far more beastmen than you would expect are born of human parents and abandoned in the woods.
