John French

A Black Library writer. He's not C.S. Goto or Gav Thorpe, but he's got a big problem: he has zero understanding of why fans of a given faction like that faction. The worst offense is his treatment of the Iron Warriors, who he writes as complete retards who only win because they're lucky and have no self-control. Us Iron Warriors players like them because they're the most disciplined and pragmatic legion; the one that will do anything to win. John French doesn't realize that good characters have goals of their own. The Iron Warriors want to build their own empires after they're finished wrecking the Emprah's. But nobody told Johnny. His Ahzek Ahriman book series is pretty good though, it's worth a read.

To summarize, HE CANNOT BE ALLOWED TO WRITE IRON WARRIORS

In this he's kind of similar to ADB. Both are excellent writers but completely ruin certain factions. In John's case its the Iron Warriors in ADB's case its the Emperor.
