If you allowed the 2eFusGre, there is no legitimate ground to prevent the K-KA from playing. Rules apply to everyone the same, can't blame Heri on that one just because he is part of the K-KA AND an admin of the tournament.
At the end of the day, you have to understand the community has changed. As sad as it is, people do not commit to regiments the same way they used to and an 'active' regiment is nowhere near what it used to be four or five years ago, with a few nice exceptions along the way of course. For that reason, tournaments such as the RGT are bound to change their approach even if I totally understand some people may not like it.
