Im newish to the tabletop, but I've been collecting for a while. I've always seen death gaurd armies with a disgusting mix of demon engines, astartes, poxwalkers, demons, etc. I really love the mixed-company feel it gives off and its one of the many reasons I chose the 14th legion. In particular ive always loved nurglings! The little lords from the lords of silence book are some of my favorite characters.
On the tabletop, it doesn't really play like the lore sets it up to be. You can be fully demon oriented with a single detachment. You can't just add a few little lords to screen or join in the joy of the plague of you use any other detachment besides tallyband. I guess I'm wondering if we are thinking/ hoping the next edition might allow for more options to include demons without making it our whole identity?
