In case you hastily clicked on the Cleric tanking thread while looking for the BIS list for gear and lessers, here’s the link that you really want. Feel free to read the tanking guide when you get done looking at the BIS list.
First thing’s first… Tanking crafted gear.
The following gear are items that you’ll want to have crafted if you plan on tanking. You can potentially use blue augments if you’re hurting for plat, but since a tank can make/break a raid, I would personally just suck it up and spend the money on the good stuff… it will make your life much easier. All of the crafted gear for tanking (with the best augments,) will be used well into tanking the raid encounters.
