The above attitude makes me cringe. Invasion or not, you might find that you get less contention working with your fellow dueling partners, rather than defensively trying to cover all of your bases. Someone asks for a training thread? Your answer could be: "Site rules state that I do not need to provide that. That being said, what exactly did you have a problem with, and can we agree on a compromise somewhere?" Of course you can make your character do anything he or she wants, but at the end of the day, both writers will enjoy the duel more if there is give and take. Coming from the point of view of someone who has judged duels, your ability or inability to be fair to your partner may end up steering the outcome if it comes down to outside judgement.
