In the beginner rules, one is encouraged to play without a Traitor. Under these conditions, does it make sense to wait until the knights have 12 swords in Camelot before determining the winner? It seems that with 7 white swords earned, the race to finish enough quests to end the game is anti-climactic.
The only situation I can think of where Evil could still win without a Traitor would be if the Holy Grail quest were lost when the sword count is 7 white to 4 black. Those 3 black swords would result in a 7:7 tie and spell defeat. In our group, the Grail gets attention early and is completed quickly, so this is unlikely.
Please help me understand this purpose of this rule.
