Where we play, there are only 2 hobby stores and in each store if the tournament does not specifically say "fun tournament", then people come with all of the cheese you can possibly put into an army, seer council, 3 helldrakes, screamer council, 5 riptides etc.. no one yells about it.
There are a few players who have done these sortve shenanigans in the past such as blatantly nit-picking at the rules just because they are pissed off at something and each time they have been disqualified on the spot. there is no room in our community for people who dont know the rules ( in a competitive tournament) or dont know how to have fun in a chill tournament.
Sure, we are a community of about only 50 people.. so it is easier to control such things.
