Right, if you don't have the new GK codex or don't scan all the forums this may come as a shocker. There is a Special Character that allows you to take Henchman as Troops without the restriction of Inquisitors.
Henchman, as standard selections - similar to many other units, doesn’t take up a force org slot.
How is AWC going to run with ruling until GW/INAT makes a ruling?
Let's get the heart of the situation, will Coteaz +2 GK troops slots + infinite Henchman be legal army?
Personally - I think it's a legal army. New and shinny aside, it does have some serious issues both good and bad.
