"1. Admins will have to make a determination based on any evidence supplied. Unfortuantely trying to pin down consequences leads to more conflict, especially with clans/players who are more interested in the letter of the rules than in fair play."
??????????????
Just state what the consequences are. Warning or suspension, whatever. I think it's unclear to have such a rule in the first place, because of peopling crashing. Every single "player left the game" situation will just be called a crash, even if it was a ragequit or intentional leave to try and get better players into the game. I don't see why a team wouldn't drop a player on purpose and have some top-tier player queue up in hopes of joining them in the match.
The rule should state that in case of players crashing, no other player signed up in the tournament is allowed to play in that match, and if they do, just let the team with no crashes claim the default win for the map. I would be infuriated if someone dropped a player because they lost a round, someone really good joined them, and we lost the map because of that. Hell, you could even drop half of your team and get DM-s who just randomly queued up...
So either change the rule or state the consequences clearly.
" 2. We found a default match time encouraged some teams to cause problems by not attempting to compromise on time because they preferred the default time. The current rules aim to make this less advantageous to teams who prefer to gain an advantage by means other than skill in the game. "
You will find that having no default match time causes even more problems. There is a reason we had a default match time in every Warband tournament for as long as I can remember. If anything, current rules will cause the exact opposite because you will get groups of people who play everyday matched up against people who only play weekends. What then? One team will propose Monday to Friday, the other team will propose weekend... going with your logic, the team who proposed 5 days gave more options, and the final date should be chosen among them (even if they could technically play on that weekend, but just didn't mention that).
