At this point, I'd just want to see *anything* on the DW line.
Like a lot of people I'd like to see the rest of the first founding Chapters filled out like the Chapters in the Core books have been. Perhaps stuff that could was from the 6e TT would work well. Grav weapons, vehicles, and gears would all be nice to have from official channels.
Hey, The Russian. It's been a while, how do you do?
Ah, none of that is essential in my mind. What is more important would be new alien worlds with new alien races to discover. Yes, I know it's a niche that RT already fills. But still. I see the task of the Deathwatch here not only in subjugation but also in intelligence-gathering. And this is something that GMs have to invest lots of time in to homebrew. Converting creatures or gear is easy.
It has been a while, hasn't it? I've been alright. Yourself?
And that is a valid point, and gear and such isn't hard to create, advanced specialties and oaths are a bit more difficult, however. Not that anything glaring stands out in my mind for the other Chapters, but a few might be nice to have.
New adventures would be good to have, reconnaisance and all of new threats. But that could also be created non-officially. But that requires more effort to create a more cohesive naratives and/or concepts for that material. I think, personally, that it will be on the shoulders of the community to further create for the Deathwatch line, since things have been quiet since the last book.
