Clan Verminus
Clan Verminus is the stupidest idea for the Skaven that GW has ever thought up. The basic troop type, whose whole purpose in the fluff and crunch was to be normal (-ish) Skaven is now a whole clan. This technically means that none of the other clans should even exist. Not many people are raging about this, but the fact that they came for Age of Sigmar means that ragers have a lot more to moan about for now. No members of Clan Jamcreermin are in it.
