I think Monstrosity is possibly why we haven't had one, they probably either wanting to keep it off of that since its new content, or are having a hard time implementing it to effect it as well, in either case, I agree. I want one, especially if it speeds up Monstrosity, because after my first 2 monsters to 60 I just don't feel like doing it anymore, it was fun at first but once you get into later levels where it slows down it just gets to boring to solo.
