Well apparently I'm part of the problem...which is odd because I don't play very often and have won one tournament in the last few years...with the 5th edition tyranid codex. Truly WAAC.
That being said I'm against ban lists, obviously. If said lists are too restrictive I won't play. If the environment is all about policing the toys people bring I won't play. 40K is meant to be casual wargame.
