I have no problem with players using every legal method of trying to win in a premiere level event, but all while being a cordial and pleasant opponent. The point of a tournament is to try your hardest to win the tournament, not necessarily to win every game.
That said, I like playing, and think a good system should value playing and winning. We need a system where the point is to win games while playing your hardest, and not try to manipulate MOV or SOS in order to get a better match up. I want organized play to work on designing that system.
