Joker while I agree fully on the painting as it adds more to the game and is much better to see accross from the table, Chase is put in a tight spot. As the TO and store owner he has to please both facets of the hobby and cant limit a tourny to painted only unless it is known well in advance.
This is one of the reasons why I go to as many GT's as I can because you know every army you will play against will be painted and effort has been shed upon it.
Local tournies im afrais it will never be mainstream for the reasons above.
