yo winning about damage on the Tank Role when the difference between them is less then 1k is kinda cringe, even more when WAR is almost Meta with his Invul low cooldown and lets not forget that for those that do not step on Savage/Ultimates that Warrior is by far the best Tank do to Dungeons with his regen and AoE abilites.

Classes changes every expansion, every Job lost something from its kit, what do you want back?
The No Mercy that stays untouched untill the final phase of the boss.
The old version of Fell Cleave where u had to build Abandon stacks.
The Pacification after Berserk?

WAR is the most fun its even been to play, and easy to introduce players to the tank role, even more than PLD i would say.

I do miss having a DoT to keep the damage up when i need to disconnect or maybe removing the gauge cost from the gap close but besides that WAR only got QoL changes over the years.

The Damage output difference is minimal and i never heard about someone being kicked or denied in a group because "Oh he plays X tank and this one hits less than Y tank".
