And what about Constantin Valdor? I think he is one of the strongest human warriors in galaxy, shame that Custodians didn't leave Terra after HH.
An enigmatic character. I wonder if GW, soon or later, allow him to reach Terra. Probably not, but who knows.
I know there's a lot of cool main characters to hope show up, but what about some of the smaller ones that have been created over the last few games? Seeing some of the Blood Raven heroes from Dawn of War, where their inclusion would make sense obviously, would be rather neat.
Lol I wish they would maybe at least make books which advanced the story line at the very least. Since there so worried about losing money from there tabletop gaming. Have to say tho Cypher would probably be the best for an appearance. He could give missions to both Chaos and Imperials since it isn't exactly sure whose side he is truly on.
Maugan 'Fucking' Ra Ulrik the Slayer Khârn the Betrayer (for the lols when he suddenly comes after you) So many more but can't put my finger on anyone's names right now. I think Brent or someone already confirmed that there'd be a few uniques, but obviously NPCs.
