First off I'd like to say I love the new tie breaker system that speeds up victories, it's far better than having to wait a day or two for the game to finally end.
That said, I've noticed it's a bit clunky when it comes to 2 people left. I will give two examples I've witnessed.
Game is nearly over, there is the mafioso and the jailor left. The jailor has an execute left (and even if they didn't could have pushed a draw) but the mafia automatically won.
Another example. I was mafia, we'd just hung Pestilence and an escort who would continuously roleblock me was left. This would have ended in a draw. I automatically won this because there were two people left.
I get that it is very difficult to account for every scenario, especially accounting for coven roles. However certain roles like Mayor, Jailor and Escort should have their actions factored into this system.
