While I'm glad this doesn't screw GRN's war, this does however dick over a lot of houses. Many people bring up Bretonia, but what about Kusari? Suddenly they have no reason to go to the taus or patrol it even if by RP they should be. Seems like there's become a limit on what house lawfuls can do for no good reason, really.
As others said, I think the community wants to see why this change is being put into place.
