Why Tank Specs?
Tank specs innately have a massively increase in survivability. This has multiple benefits in Legion Remix:
A lot of damage in Legion Remix comes from passive, flat damage effects.
Heroic Tier Open World content is very rewarding and have very hard hitting mobs.
Infinitely scaling Mythic+ gives fantastic rewards and the incoming damage scales so much faster than enemy HP.
All you need to do is survive as someone who has farmed a lot will just carry you.
The long story short is the survivability is good and you really don't need the damage!
Damage Procs
Tanks have a lower DPS output than the DPS role. Therefore, effects which give flat damage effects will give Tanks a higher percentage damage increase than the DPS role. This means that one of the biggest weaknesses of Tanks is overcome in Legion Remix.
Many have seen that the best Artifact throw is typically Twisted Crusade and the majority of damage procs are flat damage effects:
Twisted Crusade
Felspike
Touch of Malice
Terror From Below
Volatile Magics
Heroic World Tier
Heroic World Tier awards more artifact knowledge due to empowered enemies. However, this comes at the cost of mobs with much higher health and damage. White swings alone will kill the majority of DPS specs, especially between 70 to 80 unless you're pulling very slowly. However, as a Tank, you can pull whatever you want, in whatever quantities you want and even some of the biggest rares!
Pull big and get lots of loot!
Mythic+
The Meta right now for Mythic+ is 5 Tanks as seen on Raider.IO. This is because incoming damage scales much faster than enemy HP in the mode and being a Tank allows you to survive much higher keystone levels than intended. You can still easily 3 chest a keystone with 5 tanks, even with lots of deaths but if you can't survive the boss you're never going to complete the dungeon.
Mythic+ drops a decent amount of Mote of a Broken Time for gearing up and Fragmented Memento of Epoch Challenges for Artifact Power. Mythic+ is also a great end game goal for players in Legion Remix as a +30 rewards the Timeworn Keystone Hero achievement and the Ensemble: Sargerei Commander's Hellforged Regalia transmog set. You'll be able to do a +30 keystone at a much lower item level if you play a tank!
