My vote is number 3....
Druids, to me, just don't seem much to make sense as a PC class. I mean, if a player wants to be a city hating tree hugging hippy, then he won't get along too well with the other players that like to do things like enter towns and sleep indoors. IMC, Druids are little more than cultists, and why should they be allowed as PCs and while no other cultists are allowed?
