I dont even understand why this is even a discussion. If any other area of the game could be overwhelmigly beaten in such a way that it became a total farce, Plarium would have done something abut it in an instant. Remember Sand Devil's and Nogdar? it took a couple of hours.
So how is it that they can't decide on what to do about this non-sense? "Oh i spent resources building my cadaver team" => Boohoo, give them people 5 chickens and let's call it a day. As if building ONE champion is the end of the world. Nobody in the whole community paid a single cent for their Corpulent Cadaver. Proof is, i have one myself, FULLY BOOKED with only copies of himself, not even using a single rare book to get it done.
All the other champions used in the different variations of the comp would have been built anyways, so this argument of having spent resources to build the team is non-sense. Even if the team was nerfed to the ground, they can just remove the gear and throw it on other people, and even then, why bother, i'm sure those champions would work anyways as they are.
