Everyone is comparing warrior to the other classes and yes, war does need a buff. idk how but you can either increase the damage buff from storm's eye or increase the potencies of the main gcd. Regardless, war has gotten a lot of subtle buffs in ShB. That being not having to stance dance to use equilibrium, thrill of battle giving conva which buffs equilbirium and storm's path heals. Nascent flash which is god tier in big pulls in dungeons, which I do agree you need an option to be able to target yourself so it's less clunky to use. Also inner chaos is a guaranteed DHC which can be saved and used at your discretion up to 30 seconds, which I also want it to not be a dps loss to use it in inner release.
Personally, I find war different and harder to play since it's lost a lot of its mitigation, but it's still really good. For example, here's me soloing Thordan EX: https://www.youtube.com/watch?v=il0yD15el3E
There are bursts parts that I don't believe you can consistently do it as any other tank. Not only that, but holmgang's application of hitting the button is really fast and you can barely get holmgang up in time before the heavenly heel after the spear.
Personally, I do believe war needs a buff, but people are blowing it way out of the water. Give it a potency buff of maim and eye/path to be like, 320 and 440 respectively. Just so it can compete with the average gcd of every other tank. Nascent flash should also be able to be placed on yourself like GNBs skill Aurora. Also, make it not a dps loss to use inner chaos in inner release. Give inner chaos like a bonus 590 potency so it accounts for the fell cleave you would be doing, just as an example; it doesn't have to be that extreme.
TL;DR stop bashing warrior so hard, it's still really good when you look at it by itself before and after ShB release. Also it's going to get buffed sometime when either NM or savage comes out like it did during Stormblood.
