I think if you check...they do rotate, You just don't get in at the right times. I was thinking the same thing for awhile, especially NDisles, seemed like (to me) that the Rooks were ALWAYS stuck with the East side. Then suddenly they were North...although I haven't seen Rooks on the West side in a couple months. Same with Mindano really. Seems like Rooks are always South or West...never north. Further more, I don't care lol
