I know it is a weird request. I do play with default settings normally. The reason for my interest in this is that me and my friends are all on different schedules and can't always play together, this setup would allow us to all have ample time to do stuff during the week and then get together and fight off the horde for a bit on a Saturday night.
It's not so much to avoid the horde, mostly because it would be an interesting public server.
