Some would say, the conclusion is: Know no fear, to be a hero. But that is taken without context and Guillaume would be ashamed. It is your willpower and goal that makes you immune to fear. You overthrow it. And you should never rely on hope but on facts. Look at Lillith. She starts to be a real hero after she loses the fear for Tendril and points for her goal. She relied on facts, she tricked him...and didn't focus on mere hope and some shivery prayers. After rethinking, Lillith could be a good interrogator.
I regret to admit, but GW seems to run on money nowadays, that's all. The figurines getting more and more expensive, strange new inventions that are as fast published even the newest books couldn't cover them up and silly monthly sets like a whole Ultramarine chapter for the price of a new car. Okay, GW, would totally buy it. Here, take my life insurance. The only good thing was to bring the publishing and translations under their own control and away from Heyne in Germany. Heynes translations were...eh...sometimes pretty silly. The Black Library books are equal the price of the old books, have a fold-out page for the front picture and are much more durable.
And the amount of colors freak me out. Come on, special colors for dry brushing? You dun need that. I hope good authors keep the 41th millenium alive, like Dan Abnett, Graham McNeill or Ben Counter.
