You didn't miss anything important. I pointed out that one of their rulings (NCO/TacAware) was the exact opposite of what @ijw had ruled as soon as we had the official rules text.
In theory no, and it's not entirely unheard of to find pairs or small groups of Warcors, sharing the same habitat (called a 'Local Friendly Game Store'). working together in a relationship that ensures adequate reward for all parties. However, in practice they are - like all natural predators, highly territorial and extremely competitive. They'll generally warn off other would-be Warcors by staging a ritual display of dominance at the heart of their territory (called an 'ITS Tournament') that may last up to several hours. The astute gamer should be able to pick up other signs of Warcor presence too. For example, single blister packs of the newer miniatures on display, and one or two well-painted Infinity miniatures in the window of their chosen store are both indicators that a Warcor is marking his territory. That, and the carcasses of slaughtered Warhammer players littering the place, of course.
