Tank changes and how it affects each tank class in 9.0.5

Blood Death Knight

Buff 10% physical dmg reduction
Buff 10% magical dmg reduction

Blood is really good in raids, they have a big smorgasbord of good survival buttons.

When it comes to M+, where you take more consistent dmg compared to raid this is a very needed buff for blood to climb the ladder. We are in the Kite meta when it comes to M+ and this tank spec is more face tank built. It will be interesting to see the future of blood especially in M+ dungeons. If there is any spec that will bring back face tanking, it is the blood Dk.

Vengeance Demon Hunter

Buff 5% physical dmg reduction
Minus 10% magical dmg reduction

VDH have been going around with a bug since testing time of shadowlands.
This bug actually gave VDH a 15% extra magical dmg reduction.

So basically, VDH got to save 5 of those 15% after this hotfix.

Nerf or buff?

Well, the nerf was magical dmg yes. But the buff was the physical dmg.
Physical dmg is the majority of dmg you take in shadowlands.

Are they still the best in M+?

Yes

VHD brings following to the board:

Uncap AoE dmg
Magic dmg boost buff
Kiting ability
CC tools

Guardian Druid

Buff 10% physical dmg reduction
Buff 10% magical dmg reduction

GD is a very tank strong.
This buff just upgrades the power of being a really tank strong tank.

Incarnation: Guardian of Ursoc
When popping this, GD will be very hard to kill and very useful in bigger pulls on M+ and raid boss situations.

Brewmaster Monk

Buff 10% physical dmg reduction
Buff 10% magical dmg reduction

In general, best meta tank in Shadowlands are the tanks that can kite and at the same time hold aggro and also defense when needed.

The issue why brewmasters not being up top is due to the big mitigation toolkit - stagger. Stagger requires face tanking and kiting disables you to be in staggering dmg.

The buff helps brewmaster a lot, it´s huge! Especially when it comes to magical dmg reduction which is the brewmasters Achilles’ heel.

This buff will stir around in the top tanks in shadowlands.

Protection Paladin

Buff 10% physical dmg reduction
Buff 10% magical dmg reduction

Got a big smorgasbord of good survival buttons for raids.

In M+ they are really good as overall tanks in different difficulties. With many helping abilities to the party and interrupts and cc.

Also, protection paladins got really high dmg and with the big physical dmg reduction and magical dmg reduction boost they got, it will definitely take them up in the tanking tier when it comes to keys up to +15.

Protection Warrior

Buff 10% physical dmg reduction
Buff 10% magical dmg reduction

Prot warriors got really good physical dmg reduction abilities.
Having a 10% extra spell dmg reduction buff and together with Ignore pain and Spell Reflection make warriors something to have an eye on in the near future.
