In this thread, please focus feedback and discussion on the tanking Essences currently being tested in the Rise of Azshara PTR:

• Aegis of the Deep
• Anima of Life and Death
• Azeroth’s Undying Gift
• Nullification Dynamo
• Sphere of Suppression

Some tuning tweaks that will be on PTR soon, noting here because they’ll be coming in as PTR hotfixes at this point:

• Sphere of Suppression, Minor: Haste bonus reduced 20%
• Aegis of the Deep, Major: Damage reduction increased 150%
