I was in a game with RadicalD, and I have to say the issues were prevalent. Started off strong, but post rate petered out. Abrasive to work with, ignored entire player characters for convenience's sake. Made things up as he went along. A real scattershot in terms of GM'ing style. Wouldn't surprise me if he made changes in his personality over the course of the story to fulfill whatever short-term goal he wants out of the other players.
