Healvotes, in comparison to normal doctors, also seem heavily scumfavoring to me.

First of, not sure if I just missed it, but I think there's no mention of the scum being excluded from the anon voting process there. Gotta add that to the setup, or noone is of the heal targets is ever gonna get attacked.

Then, taking away a doctor also takes away one town player's ability to claim tpr, or to cc. Direct CCs are a townfavoring mechanic.

On top of that, healvotes are much easier to predict than one indivdual player's choice. You are dealing with a majority here, and this majority even has to make sure to not wildly vote different players, as that would result in the final target having to be chosen by the host.
