I think a crucial factor of any fight is how quickly you can size your opponent up, which is why it's best of five. However, if general opinions differ, I don't see why we can't turn the number of rounds up.
Ah, figured the reasoning went something like that. Which, I'll say again, is fine for round robins*. But, as I know you're well aware, high-level dueling isn't about who clicks the buttons the fastest or most consistently--it's the player's tactics that win. And basically, with only three kills to win, that quality has little chance to shine. An actually-realistic example of a first-to-three match: You block, stupidly feint your first strike, opponent spams, you die. You attack, opponent chambers, you die. You have no idea if it was intentional, so you adapt an anti-chamber style. Opponent spams into your anti-chamber holds, you die. GF.
Yeah, unlikely to happen, but two luck kills/deaths isn't unthinkable. Then again... Huh. I just remembered, people don't die in one hit. Hmm. I'm too used to Native dueling conventions/wearing a dress. Right-o, disregard anything I've said until I test dueling with armor.
* Also realized I'm assuming the Champions tournament has robins, followed by DEs. Which is probably wrong -- kind of used to fencing conventions also. I need to find something to eat
