Well, that was kind of the whole point. Place it in the highest populated areas.

It was immense fun for those that looked past the "oh noes I can't do what I normally wanted at this exact moment in time" aspect. When I was 'alive' I cleansed everyone I could, and attacked every zombie in sight. When I was turned, I attacked everyone I could. The best would be when 'd go up to a priest/shaman/pally and /help /poke, or /s help and they wouldnt' do anything for me, then when I turned, they were my first targets.

I think people just needed to lighten up. There was still plenty of things to do, and plenty of places to go, even as lower levels, where you could continue to quest, level and get gold. After all, no zombies could follow you into instances.
