It is too easy for TW to end in a tie. Thankfully, our guild has won both on ships. First TW w3 had 1 1/2 fleets left, 2nd TW we had 6 1/2 fleets left. I would suggest something like 10 banners for defeating enemy on 1st try, 9 banners on 2nd, and 7 banners anytime it takes 3 or more times. This would make it far harder for TW to end in a tie.
