I voted yes... but I think there should be an 'indifferent' choice in it.
While I hate and dispise ZE's, I don't mind them in the rotation everyonce in a while. It's when ZE's get voted on for 3 maps in a row that makes me change servers. Definately remove fast zombies from ZE's.
ZM only server? great idea, but would have to really get people to vote and discuss which maps should be cut from teh line up. I'm not suggesting to cut them now, but cut a few when a few new maps get put up so there's still a nice number of maps to choose from.
