I agree, this was a BS let-down.
Why didn’t they simply release the second Broken Realms Book as Broken Realms: Sigvald and include all the rules for the new models in there, as
@Erta Wanderer says? That’s what they did for the new Admech models they released around February-March time - they simply included the rules for them in Psychic Awakening: Machine War, which Admech players were going to buy anyway.
I sincerely hope they give Fyreslayers a second wave with accompanying Battletome after this, because we Sons of Grimnir are in far greater need of reinforcements than the Chaos God of Transvestites.
And I agree with
@Grotpunter, certainly Maggotkin, Beastmen, Legions of Nagash and Nighthaunt could all do with a boost, either through Battletome or Broken Realms Book, as they’re the most underpowered factions right now (DoK and Idoneth already got some stuff out of Broken Realms: Morathi)
