Whenever the two forces meet, champions will fight a duel (usually to first blood) in remembrance of their two respective Primarchs fighting. Probably won't be an issue in the Kill Team, but there would still be some initial dislike to overcome.<br/><br/>They also have a lot of secrets once they get up through the ranks.<br/><br/>If you want someone that's more straightforward to play, there are probably simpler ones.
