It was just an after thought yesterday, but wouldn't it be fun to have some epic level Whisperdoom quests? She makes an appearance off and on in heroic quests, and having a newly designed small chain of dungeons revolving around an updated storyline (maybe like GH's revamp?) could work well.
Of course, with the u19 enhancement bugs, the long running ladder/lag issues, the new TR changes, and everything else mounted against this game by their own doing is asking a bit much for something that, really, is more or less just for gits n shiggles.
But a CR40 (or thereabouts) whisperdoom would be kinda enjoyable, especially if made with an end raid boss fight akin to Harry.
