There’s more than 1 way to be strong town that isn’t “be town leader.”
Hell sometimes “town leader” types, or those that try to be one, can be extremely detrimental to town- especially when they suck.
You got players like Illwei who you’ll never see demanding someone gets voted out or derail an entire game for it, but if you see her reads and the results you’ll see how accurate they are. I consider her strong because of that since her vote won’t typically be wasted on town and she won’t fuck an entire game up with a stupid move.
