Uh, no. Khorne is about mastery of all forms of combat - ranged, close, orbital bombardment, etc.
The whole close combat thing is really comparatively new. Khorne is the new book is much more in keeping with the fluff than it was in the 3.0 or 3.5 books.
The Choppa rule was silly and it was a save modifier in a game that had otherwise gotten rid of them. It makes sense to get rid of it. Besides, point for point, Orks are better against Marines now than they used to be.
I don't agree 100% with the changes (generic demons irks me), but overall they're on the right track.
