This is exactly what I mean. Double NK pretty much guarantees a Town loss. 5 Mafia does similar. Vampires ruin the ranked games.

On the other hand,

It could roll as a Mayor or Retri. It could roll as a Veteran. It could roll as a Transporter. It could roll as a bodyguard. It could roll as a Medium.

This swings the Ranked games immensly and less skill is required. Double NK is stupidly broken, but this allows it to roll. 5 Mafia is also broken, but this allows it to roll. Now, you don't know if the game you'll enter will be shit or fun. You can't guarantee a balanced game. On the odd occasion, I'm sure it will balance the game. Note that using this as a replacement for RT wouldn't work because even if it's more likely to roll a Town role, it can be detrimental to Town.

In my NB blog, I don't believe I mentioned this. It's because I'm generalising the NBs into what would be best for them. Not what they want - actions are always dependent on the player; will I gamethrow, will I not? It's best to calculate off of what should happen and what is most likely to happen. NBs are not, truly, Town-sided.
