Reasonable buff to war

[ForteNightshade]

Excalty, Holmgang can be nice for one Monolith, after that its basically kinda pointless till the end where you are saving 1 cooldown for each of the tanks for soaking it... but honestly that cooldown when you need it will be up again for the final Monolith (rampart).
When it comes to DPS Im not mentioning DPS, that's up to SE. WAR should be the lowest dealing tank because it has the lowest skill floor/cieling of all the tanks now with GNB definately the highest and only getting a small amount more damage than WAR. That is of course if GNB can keep uptime on the boss. If they can't and WAR can land all of its IRs with no problems then they are even. PLD on the other hand... I can't think of a scenario where WAR would be dealing more than them besides maybe AoE? But that's padding and I think PLD is stronger in that aspect to (slightly). When you factor in raid buffs... WAR only is affect greatly by 5, Brotherhood, Embolden, Devotion, Technical Finish and Trick Attack. Battle litany and Battle Voice have low effects on a WAR compared to all other tanks so if your group is running a DRG/BRD you are missing out unfortunately.
However as you stated, its fight by fight basis and on E4S WAR can get brutally cuck*d by mechanics and waist IRs with how akward the fight can be for them. Missing an IR is just a death sentance to a WAR.

Difficulty or complexity should never be considered for job balance. All it accomplishes is punishing you for playing an "easier" job, which in turn, makes people not want to play them. It also isn't anywhere near consistent. Ninja and Summoner are by far the most complex DPS yet neither compete for top tier in their respective category; Summoner getting absolutely bodied by Black Mage.

Ironically, you could make a case Warrior is actually much harder to optimize than say Paladin due to how clunky Storm's Eye, IR and Infuriate can be.
