Warden Tank Set Theory Craft - Frost Staff Tanking

x2 - Iceheart x5 - Brands of Imperium x3 - Willpower w/Health x2 - Crafted Ice Staffs w/ Shield affect

This is mainly for 4 man vets and potentially off-tanking trials down the road. Considering a 1h and shield in back bar, but I'd really like to stick to the Frost Staff build theme. I don't need to main tank trials.

Thoughts? Suggestions? Prayers?

Greatly appreciated....
