So, explain why the game needs to be twisted to meet the requirements of people apparently too fickle to play as intended?
It has never been about playing the game as intended...it is because playing a game for 12, 13, 14, 15, 16, 17 hours is way too long for many people (not just me). The likes of Soontir and Vanor shows exactly how welcoming and understanding some in the community actually are. They don't care how the game effects others as long as it doesn't bother their perceived perfect little world.
You really need to scale back your rhetoric, as you are winning over nobody with this argument. And I say this as one of the people who actually agreed with your basic premise about 16 hours being too long for a tourney, while also agreeing with the people who say that 12 hours to run six rounds of Swiss is a disaster of clock management by whomever ran that tourney.
