Why all the hate for chaos? It's the only system where success or failure is rewarded fairly. You win, you get followers, power*, and more guns. You fuck up, you end up as a chaos spawn. Totes better than an already-laid-out-for-millenia arbitrarily arranged system where the top 1% are rewarded richly, and fuck the other 99%. Anyone with backbone & wits enough can get a gun or 'choppa and work their way to the top. Daemon Prince, baby!
