Percentages

Overall, I don't have much to add about Revan. Percentage-based defenses: you encounter them, and you get annoyed. They don't work, and you get annoyed (and you're such a cool guy with 99% defense, and then you get killed on the first night randomly, yeah...). It's often impossible to fix the situation, and it's also impossible to account for all the risks due to their sheer number. One-time defenses: unfavorable randomness is still possible. But practically any failure can be corrected, and that's the key point. And in general, the fewer random numbers there are, the less likely it is that randomness will become decisive in a game. So, on this issue, if there's anything I agree with Arandor on, it's that these defenses shouldn't be overused, so that their number is reasonable. Although in most games on HW, it was quite reasonable. Without defenses: yes, please, you can play without defenses. And you can also create mafia setups based on the principle of "9 villagers without night defense, 4 mafia with kills, 1 serial killer with a kill." Then you can establish a practically perfect balance, and nothing will drag on. Only no one will want to play it. Here, it's obvious that you need to find a golden mean between the presence of certain defenses and the interestingness of the setting. And this golden mean does not lie in the complete absence of any defenses, believe me. Although in some individual games, you can do this if there are other interesting features as compensation, but in general, it's unlikely to work.
