I don't disagree with the sentiment of allowing ties versus not. It would also resolve tourneys faster. I personally am not super pleased by the fact that you can take a less useful option to edge out the tie win (Taking the 4th province, versus taking the stronghold). I wish it was "Provinces broken, up to 3". At the moment, I cannot think of a good reason to try and break a 4th province over trying for their stronghold, that isn't either tie breaker, or a delaying tactic. There are minor gains, and its better than not swinging, I guess, but it isn't something you would typically do to try and win, which the tiebreakers should cover.
If this was old L5R, people would be fuming over the whole Honor thing not counting (the current 'alternate' win conditions), but I think its fair in this game, since you are likely to break provinces while playing honor or dishonor.
Initially a tie resulted in a double loss in the Kiku Matsuri. I'm guessing they just didn't want ties.
