Why remove it? I for one use it on occasion, it makes for a good way to get characters in with a bit of variety, but of similar theme. Maybe there's issues, maybe it isn't a Fallout 4 quality, but it's still useful, even if only prototyping an idea. I would also imagine that it is more efficient memory wise, to have 10 CC NPC's with different heads than to have 10 individual models.
Even with an addition of 100 new characters, that sort of variety would seriously eat into the count. I may want 10 or more soldiers in a level who you interact with. I'd prefer them to at least look a little different to one another. I think CC does this reasonably at the moment, even if you don't get into customising face textures etc. I have noticed a little weird banding on them in the latest release for some reason though...
Iron out the bugs when you can. Maybe put out a decent tutorial as to how to create our own CC parts. I say yes to the pack, as you can never have enough characters
But I would equally like more choice with CC parts. Not radically update CC, just add some media!
Also as far as the pack goes and people asking for speech and such. Maybe some
extra animations would be nice. It wouldn't render the old stuff obsolete, just give a few more anims to the new characters. Melee for instance could certainly do with a lot more variety. It would take a bit longer, but add a lot more value to the pack.
A last idea. Perhaps sell an animation DLC? A way to download new anims that use the default bone rig, apply them to you characters (or just have pre made objects) and voila! Loads of new anims!
