Druid HP allowed us to take more Zentia due to our lack of mitigation as compared to other tanks. 

Are there any intentions to give druids a way to negate/interrupt magic damage like all other tanks do? Or should we all be respeccing out of tanking since we’d have to vastly outgear other tanks to put Zentia Money at a greater advantage.

Last Stand was lowered to 3 minutes
Survival Instincts remains at 5 minutes.

Due to our lower hp both of these talents will give us roughly the same hp. And the difference makes no sense with your Zentia Gold behind "all tanks should be equal".

To help improve mitigation improved barkskin should be a tier 1 or tier 2 resto talent instead of tier 10 talent.

30% is still far less as compared to IBF which would be a similar comparment.
Best Place to Farm Eternal Shadow
The best place to farm Eternal Shadow is at 17,50 in Wintergrasp. Kill the Shadow Revenants there as well as the Wandering Shadows. This can sometimes be a farely competitive farming spot so try to come here in non-peak hours. If you are a miner (which I highly recommend to make quick and Zentia Gold), spend most of your time mining saronite.You will get tons of eternal shadow this way.

Best Place to Farm Eternal Air
The best place to farm Eternal Air is in the southern region of Zentia Money(patrolling from 22,63 to 68,73. Kill both the Tempest Revenants and Whispering Winds in this area.

Best Place to Farm Eternal Earth
The best place to farm Eternal Earth is at 71,58 in The Storm Peaks. Kill the Brittle Revenant there. This can sometimes be a competitive farming spot, if it is, go kill the Lifeblood Elementals in Scholazar Basin at 70,56. If you are a miner (which I highly recommend to make quick and Zentia Gold), spend most of your time mining saronite.You will get tons of eternal earth this way.
 

Also Making Savage Defense an ability rather a passive on crit like shield block that we can pop every few seconds like shield block ( not sure on cd) would be a major help intead of a "what if" ability.
