Andy Chambers
Andy Chambers is a good old guy who quit Games Workshop in the middle of 3rd edition of Warhammer 40,000 as the corruption became ever so more noticeable.
He wrote a lot of balanced codices. One of the more famous ones was 3rd edition Codex Orks. Although the codices were a master piece of character, fun and balance, the wording of the rules was shoddy, ambiguous, contradictory and even missing at times.
