5 important traits for a growing guild

[Gardur]

We founded Casual Scum to have some fun and kill people in the snow. Since our modest beginnings we've grown bigger than we anticipated so we end up constantly reevaluating our plans to accommodate our size. Since I don't like to do things half-assed I'm studying the different guilds, their structure, and their qualities/deficiencies to do the best job possible leading my pals.

For science.

List the 5 major traits you think are important to a growing pvp loving guild to be successful. You can list more than 5, mention which guild you think is doing the best job, and even offer some criticism.
