I agree with taking NK out of the ranked role list. They had a very low win percentage and only caused slight confusion for town. How about replacing the 4th RT with a second NE? This would guarantee more confusion for town, and give another person a shot at gaining elo, while lowering towns current (extremely high) win rate. Would make it more fun for players. I personally love NE, so maybe this is biased, but I don't see how it'd be any worse than 4th RT instead of NK. Also, mafioso NEEDS to be reinstated for ranked. Having GF jailed n1 ruins the game for mafia. Sure, hypno could give a player attacked/healed or defended but very unlikely that it actually works out.
Town is too overpowered in the current patch, and should get rid of RT4. I don't agree with bringing back NK because of its low win rate, but something needs to happen. I do like having "new" mafia roles in ranked, as it adds some extra confusion, and strategy, but having only GF is bad because if he's jailed and there's no mafia kill, there's no chance if jailor/escort is smart enough to try a second night.
