It would be sad if it is. I was hoping to submit some character classes and that sort of thing once RMu came out and we had final stat for things like professions, spellcasting mods, etc. But as JDale noted, it is hard to write for a moving target, so I've been holding off. And I'm not sure if the GC would be the appropriate forum for things like new classes (would be good to know ICE's vision for that).
I will have to go comfort myself with some lovely spam, spam, spam.
