I've been looking at the design of the warband theory myself lately and have come up with a couple of options that could be inlcuded.
I like Frogbear's idea of naming Retinues as
Warbands - it's much more grunty - so consider it done.
Black Legion, you may be a happy camper as I've flipped my thinking on your idea and I think I've come up with a way to incorporate your favourite unit - the
Slaughterfiend. Instead of adding them to a retinue we could simply have them in their own formation and add berzerker units
to them:
Slaughterfiend Pack - 4 Slaughterfiends and 4 World Eaters Berzerkers = 300500 points
This way they are integral of their own formation. I think I'd just need the exact stats and cost them correctly. Any ideas? Where did you get your stats for them?
My other optional idea I've been considering is the
Blood Slaughterer. At the moment I think we could have both an upgrade of 1-2 to a retinue and a free-standing formation of 4. They could help beef up a foot Zerker formation and they could fill out the ground-based units for a Drop list if players choose that option.
What would these things be costed at? I have them down in WE 1.1.1 as approx. 83 odd points. Would 60-75 a piece be too low a cost for them? I was thinking 4 for 250-300 perhaps? They're a little better than a WE Dreadnought(50 points) but I don't think as good as a Khorne Defiler(costed at 100 right now, at least)
Anyway these are my recent thoughts.
Any comments?
