This is a list I have been looking to make for myself on the first tank set I would like to gather. I have only so far looked at 25 man Ulduar loot, no hardmodes. But as im missing a few pieces, hands and neck. And I have some spot to think about which piece I would like the most. This is still a work in progress. I will come back to this as soon as I have had time to look on 10 man loot as well. And take a look at Rawr and play with some gear setup there.
Lets call this an indication of where im heading.
