What do y'all think of the idea of creating a new grand alliance made up of Idoneth, Umbraneth, Daughters of Khaine, and Skaven? I've always felt that those factions didn't really fit well within their current Alliances. They are duplicitous, not interested in a full Order, Chaos, Death, or Destruction victory and mostly pursue their own agendas. You might say "Well they fight each other as much as they fight other potential Alliances and don't work together regularly." I think though that you could just as easily say that about the other alliances, except for perhaps Order. Also, their means and individual agendas often align in the sense that they mostly just want to be left alone to build their own power base and are willing to make accommodations and negotiations with other factions rather than being intrinsically opposed.
