Your revised wording doesn't cover what I think you hope it would. As I understand it, you want to make sure that if a couple is fighting in crown, that they're fighting each other. More to the point, if a competitor in crown is also another competitor's consort, that they fight reciprocally for that competitor and not for a third party. However, your wording (I think) sets it up so that no member of a couple may fight for anyone else regardless of whether both members are fighting or not. *That* is, I think, equally damaging and should be avoided.

Of course, this doesn't touch polyamorous relationships and the fighting/consort pairs that could be legitimate in such a setting. But I've had a hard day and don't want to touch that can of worms apart from bringing it up. :-)
