Naturally I understand that even addressing this question is likely to rapidly devolve into a "Wally/Donna" complaint thread, so right off the bat we'll address them, so that (in vain hope) no one else will need to do so. There have been many comments from the higher-ups regarding their future inclusion in the universe and justification for their absenteeism... as such, I'd like to avoid that conversation to focus on others that have escaped notice.
I've been collecting the names of the missing as seen here: http://www.comicvine.com/myvine/theoptimist/dcnu-faces-on-milk-cartons/75-33395/?
Now that we're over 6 months into the new universe and have had a little time for universe exploration and a handful of cameo inclusions, what major players have yet to take the stage? Who are some of the minor obscure characters that you are hoping will find a new place in the new world, and how do you see them? I'm always looking to add to my list, so please toss out those favorite gems of characters! Who knows, they might've already snuck their way into some unread pages!
(As a note, I've removed many characters from the aforementioned list because of their appearances; some others remain because their appearances are upcoming or were merely mentioned.)
