I totally get being more interested in expansions to vanilla content than in new stuff. DTD is an expansive game as it is, and for many people, more classes and more dungeons might feel like too much of a good thing. Although I think the new stuff is pretty fun, and people will warm up to it if they try it.
We made a decision early on to not alter existing vanilla content. We want to keep the mod as unobtrusive as possible.
You'd probably like the new challenge mode:
We don't have a board, exactly. Work is coordinated through
Trello. We have a public one for people who want to test stuff, and a developer one for people who want in on design and don't mind being spoiled. Invitations are open to everyone, it's not an exclusive club or anything.
