Mage Tanking Guide

I'm putting this thread as a placeholder to gather info on Mage Tanking in Rift.

This the best guide I've found and what I've been using as the basis but use a really simple layout and rotation as there are a lot of features I'm just not sure when I would need to use yet.

I believe a lot of tanking is still based on INT so the BIS sheet is pretty accurate to that but I know there are better tanking specific items not incuded on the BIS:

Questions:

1. Is there a 'Tanking' seal for Mage or is the INT seal the best one?

Please post any other strats or guidance you come across here so we can all benefit.
