Well this will give them a chance to add more back story to the new pups, they do hate the dark angels after all. Besides Practice makes perfect!
Well i don't think that will be a Problem as long as a High Ranking Chaos Champion or perhaps a Daemon Prince of another Faction were to lead them, just to help put fear into both the new Recruits and foes alike. But i have no Idea if that would work or not.
Theyre kinda interesting but not all that much. Their sole trait is that they turned renegade after being cursed to hear the voices of cultists unless they kill. Doesnt appeal to me all that much.
Well I'm just saying that Eternal Crusade could be a great way to add more Back-story to this group of Renegade Marines, How do you think the Blood Ravens Chapter Became so Popular? Nobody knew about them that much until Dawn of war came out. At least that's how I found out about them. But It's okay if you don't agree as I don't know if a lot of people would like to play as Crimson Slaughter Marines, Because it seems people like the Red Corsairs more than the Crimson Slaughter, due to the Red Corsairs having a much more Interesting History with the Badab War and them being Notorious Pirates and all that.
I think Red Corsairs would be cool not only lore wise, but also tactically as WELL as aesthetically. Since they would accept any rogue space marine into their ranks, it could work for having a variety of different looking armor sets/colors that are based around the Red Corsair main colors. Also, having a warband that was more "speedy" in their method of war would add a nice change to the line up we already have.
