Master of secret stuff
They should have probably done them like in the monstrous Arcanum book, add in a scroll of binding allowance of 25%. It does make me wonder if 9th ed will include scrolls as binding as standard thing.Like you Brock, I'm still not getting all this sorcerous pact stuff, nor am I really getting all this "take it out of special". However as suggested, perhaps a limit to how much of your special is the answer.
I don't think your going to see as many Kdaai's as you think, I imagine the people who bring the power lists are the type who run around forgeworld moaning about forgeworld rules and refuse to attend events that use them, you will probably see a few, just not one in every army.
You not taking your Jugger list?
