Seriously though, on question 3 (the only question that doesn't have a completely obvious answer), democracy ruins games of dom3, as I'm sure veterans will attest. So many games are scuppered by votes and attempts to gain consensus that's it's not even funny. I see games that can barely even start because voting on settings is going on.

You need a tyrannical but detached admin and in large team games you need to communicate frequently but never, ever call votes.
