Sorry, we're all busy and that includes both RL and work on the mod.
When you say the DB follower, I assume you mean the Dark Brotherhood Murderer. In which case, the answer is no, we ain't touching that. Though we might have more than one of them, in each Sanctuary. What could have been improved with them? (We are open to suggestions, though this mod is more about extending the lore and storyline/questline, than about altering the rather useless follower - I personally don't use them because, hell, I'm the Listener, I can kick ass and take names all over the Empire without leaving a trace! XD) But yes, if you have ideas, share them!
