With the launch of Stormblood

Eh not really, as MT war is kinda inferior compared to pld/drk, for magic busters we only have thrill (which isn't a big mitigation on its own) and vengeance. With high defiance uptime yes war has a really good mitigation, but there's a reason why people don't have wars tanking in defiance for a long time.

Ok, let's count what PLD has for magic damage. Rampart...and Sentinel, the first one on a 90s CD and the second one on 180s. And of course, Hallowed Ground.
You don't need "high defiance uptime" to pop Inner Beast either alone (As poweful or Rampart) or on top of Vengeance (More powerful than Sentinel) and/or Thrill for each perfectly scripted tank buster. WAR is also able to refill a lot of HP instantly after a big hit. And if you really, really need the mitigation, you still have Storm's Path...WAR is a better "magical MT" than PLD. And for obsessive-DPS-people who will answer "But, using Inner Beast is a DPS loss compared to Fell Cleave"...well PLD is a DPS loss compared to any other tank.

In fact you can easily match Rampart with Storm's Path+Thrill+healing and Sentinel with Storm's Path+Vengeance, making even Inner Beast less required.

The only fights where warrior is good in the MT slot is where the tank busters are spread in a way that you can holmgang every alternate tank buster (like a12s), so you can stack thrill + vengeance for the other ones.

Warrior is a "good" MT in every fight. Not "the best", but still a better MT compared to PLD than PLD is an OT compared to WAR.

There aren't many fights where bringing double war is optimal.

There's pretty much none, but for very different reasons than their personal prowess. (Not stacking jobs, non-stacking debuffs, etc...)

That's why i said... War doesn't really care what dmg inc type it is.

Magical dmg? Pld is weak
Physical dmg? Not the strength of Drk
While warrior _can_ use inner beast and /lol-macro

War mechanic is maximum flexibility + good dmg, makes him a win for every second tankslot

That's the main issue that I also want to see resolved. Even if we place pld/drk as the MT type tank they're still terrible together. To begin with I never liked the idea that war is the one and only tank that has slashing resist debuff, considering all the tanks have slashing type damage. Either give all of them slashing resist debuff or remove it from warrior. Storm's eye isn't the only reason why warrior is a good tank, but it's one of the biggest reasons why pld/drk combination is comparatively terrible.

(On a side note it seems like double war is possibly optimal at faust z lol)

That's why I think it would be a good idea to make them perform better as OT, so that PLD/DRK is not clearly inferior.
It would also result in more setup with WAR MT - PLD/DRK OT because some players likes to MT but don't really like PLD andr DRK.
