No, not beyond the fact that he's only been lynched once and I'm willing to try it again.
And I agree, I don't want to waste a day either, but I don't really know what else to do, since it seems like there isn't a ton of assassin fire power +/- the bounty hunters seem like they can't actually do anything. Like, it has to be possible to eventually get rid of someone, and if we can't go for a Capri lynch, and no one besides me thinks it's possible for zombie-Mel to be wolfy, then idk.
Maybe I'm missing something here, but based on the way the game seems to be laid out with low death at the beginning and people getting added, I'm not entirely convinced there are other wolves in the game right now besides the ones we know about. So, I am voting for one of the ones we know about.
