So GW/CA announced that new daemonic units would be coming to Warhammer, and I for one am personally hoping to see the Daemon Brutes from Horus Heresy ported into the fantasy setting. DoC don't have any monstrous infantry, plus it's another undivided type of daemon. But I'm kind of hoping that they're kept exclusively for Be'lakor (assuming that the dominant theory of him being the 9th LL is correct and CA doesn't bamboozle us), the Soul Grinder too. IDK, I just think it would be nice for the first daemon prince and the DoC roster to have some unique units all for himself, especially since each monogod roster is going to have some unique stuff separate from each other. Some fully unaligned monsters that only his race/faction get's access to would be cool.
Pic of the daemon brutes for those unaware.
