Being the strongest tank 3 patches in a row isn't really an interesting or good niche.
I'm not saying that WAR needed help with Abyssos mechanics, I'm saying that Abyssos mechanics show that WAR's mitigation/healing/invuln is actually balanced when the devs don't just put the simplest tank mechanics into a fight and call it a day.
And yet people still chose DRK and GNB over WAR in DSR. I guess extra uses of Holmgang don't actually make much of a difference there, because anything that you can invuln in this game can be easily mitigated.
