I never really died as Mayor when building was permitted as no one was able to get through my defenses. So, this would be a good re-implementation but instead of having a maximum of 4 fading doors, I suggest lowering it to 2.
Also, I agree with Mayor not being played as much. Every time I hop on, there is no one playing Mayor. That's quite surprising though because it's not hard surviving unless someone is spamming hits on you.
