Watch them toss all the various factions into the blender and spit out:
Imperuim Super Friends
Elf Super Friends
Chaos Evil Super Friends
Uhhh the other random Xenos Junior Varsity uhhhh... Cool....Things!
Yup did that already.
Three "Factions" are Imperium, Chaos and Xenos.
Imperium is very padded out with 6 Astartes (Space Marines, Blood Angels, Dark Angels, Space Wolves, Grey Knights, Deathwatch) then Imperial Guard, Sisters of Battle, Custodes, Sisters of Silence, Mechanicus, Imperial Agents and Knights.
Chaos getting the stinky end of the stick again, has Daemons, Marines, Death Guard and Thousand Sons.
Xenos (wooo catch-all), gets pointy eared padding with Craftworlds, Harlequins, Dark Eldar, Ynnari, Tyrannids, Genestealer cults, Orks, Necron and Tau.
Xenos get a cult group in their faction but we can't have a Chaos Cultist group in the Chaos faction? Bah, bad show GW. Bad show.
