First things first:
Yes, 40k needs a cleanup, there are a lot of problems with Rules n stuff but thats not the subject here :P

So, AoS will basicly get three sets of rules: Open, Narrative and Tournament.
I was wondering if this could also work with Warhammer 40.000.
A lot of new Books added very fluffy rules to the armies (KDK, Tau, the new Space Wolfes stuff) and in most Supplements you will find new Altar of War missions to play.
So with the next edition of 40k could you imagine having it some more fleshed out rules for unbound, lighter rules to play narrative or stuff like that?
