I'm of the mind that any model on it's own should be allowed. I will not ban a single model on it's own merits, but I will comp it heavy if it needs a heavy comp. The full comp list will be listed this weekend, but to give you an idea, Karl/Malekith/Nagash are all in the range of 170. Which means if you bring that filth, it's very hard to fit other filth in the army.
I feel the Swedish comp is a good baseline to remove the truly broken armies, but I don't agree with giving armies extra points other than that which they earned in a game. I feel it caters too much towards the better generals and list making tacticians. I want both players to be able to look at the table and get a good feel for exactly how they are doing in the game.
