This is a seriously old post that someone drudged back up so let me just state something very clearly: Leviathan as a server has changed drastically since Akomplice first asked his question. The best players all relocated to other servers. Leviathan in general is a social and casual server. If anyone is looking for a serious raiding presence (as stated by the OP) then your ultimate bet would be to check out Gilgamesh instead.

Also, Advent Union had the best history since 2.0 with being the server's top guild. AU was by no means a laughing stock, and it's quite disgusting what this server did to AU. What I had stated many months ago was during a period of rebuilding which had started once Final Coil was brought to the duty finder. However now, because of the blind words spewed by casual players, this server in terms of top raiding guilds is completely dead.

If anyone thinks I'm just talking out of my backside, I encourage you to look at the server's entire raiding history and note the names and dates of FCs and their clears. Please also be drawn to the lack of FCs on the current content patch (3.0, as I'm sure this post will find its way once more to page 10+) versus the abundance of Linkshell groups and the massive red flag that this draws. Note also at the time of this post, only four groups on the entire server have downed A3, with one of those being yesterday and the new AU hasn't even done so. Simply more proof that this is not the server to be raiding on.
