Exactly, Universal. Wanna be Raid proof? Building your Tribe on high ground (like the Mountains at Mainland), so you can see things coming your way. Surround your Tribe in Castle Walls, with a Castle Gate. Block off entrances to precious Ores like Mithril and Chromium, so you'll hold a monopoly on them. Regularly patrol the around the Castle Walls. Never think that you're safe, that is a weakness.

Do those things, and the only way you'll get Raided is if the entire Server just so happens to show up on your doorstep with pitchforks and torches.
