I have my own personal reasons to despise what he does to Warhammer 40k especially since he just loves to butcher the Sisters of battle for NO GOOD REASON. Seriously, Wtf ward.... Grey Knights need to bathe themselves in an entire fucking coven of sisters blood... to do what? Protect them from the Chaos corruption? You already made them impervious to corruption and can somehow take down bloodthirster one on one. Why the F*** do you need to protect the incorruptible from Corruption with the blood of the Faithful who F*****g work hard to make themselves faithful?
Seriously, Why sisters? Why not the Rivals of your beloved F*****g Ultramarines the Imperial fists? Or the Dark Angels? You know?... the ones which someone else can easily salvage with their superior writing?
