There are this Bretonian Knights showing up around Blood Keep to help some Empire County (don't remember which). I have nothing agains them, they are cool, but there is on thing. This nation that they are going to help changed theyre god and now they are in love with Slaanesh.
Now you can understand the pain when you are playing with County of Wiseenland and almoust full stack of Bretonian Knighs is showing up on your back, and they are in war with you.
Cause they are going to help fight against Chaos, shouldn't script take it into exeption that they wan't show if nation goes against Empire?
