Andy Chambers
Andy Chamber, a good old guy which quit Games Workshop in the middle of 3rd edtion of Warhammer 40k as the corruption from the lawyers and economists became ever so more noticeable.
Andy Chamber wrote a lot of balanced codexex among the more famous one being 3rd edition Codex Orkz. Although the codexes were a master piece of character, fun and balance the wording of the rules were very very shoddy, ambigious, contradictionary or even missing at times.
