And what are your other CDs doing? All three bosses barely do any auto attack damage. While that doesn't make Holmgang crap—nor did I imply it ever was—it does make it less impactful. What made Holmgang stand out is how many busters you could shrug off. That isn't to say it should have stayed that way. Frankly, it was too good in fights like O8S and O12S. But my point is you can't point to it and say how much of an advantage Warrior has now.
Not complaining. I'm pointing out Warrior is the only tank that requires a second CD when the others don't. While Vengeance lines up for the first Stonecrusher, it isn't always up for each one you take. And frankly, it's better used for the auto attacks in lieu of sitting on it afterwards.
Yes, it's your comp. PLD gets nothing from MNK and RDM during its Holy Spirit window. You also have the best WAR comp outside of NIN as they all increase flat damage compared to BRD or DRG.
