Ok folks, here is a question for you to consider. How would you feel about playing a game against someone using Chaos Marine models with the SoB rules to represent a themed army of psykers or something similar? I ask this because I have had the WH rules since the latest book came out, I love the way they play and feel, yet I dislike the fact that the entire army is metal which cuts down on conversions and variety. I have been thinking of making up a Sisters list but making the army into something like the Brethren of the Void or some such, substituting CSM models for the Sisters. Would this work? I mean theme wise, and 'feel' wise.
