The last job that needs a boost is war.
It's less about needing a boost, and more about wanting something more for WAR to work on, that doesn't feel simply like a sidegrade, or at least has some sort of significant practical application.
The Limbus set gives two pieces that are very minor upgrades, almost side grade pieces, in its Legs and Head. There's a case to be made for making a 100% auto attacks crit rate build with it, but since you won't see significantly increased WS frequency, it's like a cherry on top rather than a whole nother cake.
Then, with regards to Hoxne, that's a big ticket item that 20/22 jobs get to go bananas over (SAM could get to go bananas over it too, if they fixed Zanhasso priority, but at least SAM gets the juicy Quad Attack set).
No telling how soon, how much, or how significant, but as they introduce new content, content that may not have the restrictions from Sheol that make WAR appear greater than it really is, the more the jobs I listed will just become the go-to choices. Not necessarily a bad thing, but you can already see WAR's "dominance" evaporate in content like Sortie and Limbus and Master Trials. Has anyone run 9-boss(or hell, even just Aminon) with WAR in a slot(with good results)? Does WAR have any real advantage over other stuff vs. the Mannequin NMs and CN HNMs?
I guess what I'm driving at, is that even pre-Limbus gear, other jobs aren't really that far behind WAR, and post-Limbus gear they're beyond it. They get to have their niche and progress to a real, new plateau. WAR has plateaued. And a huge part of its plateau, its entire itemization, is given now to everything else for a "small" price.
Without content that by design and restrictions favors it, it becomes sub-optimal. It's never gonna be bad, but there's something I feel I am failing to communicate about how bad it feels to be able to be so good in so much, but then never be able to go into the highest end content as more than a novelty. Or you know, how bad it feels to have the efficacy of WAR's SPs disappear under optimal buffs (Brazen Rush is already only +80atk with 30 seconds of getting to use slightly more Store TP/Empy set effect gear if you wanna tryhard) - (If you're already 9-lining WSes then Mighty Strikes is only impacting auto attacks(or only kept in good grace by things like WS wall) :/). Like heck, if you think about it, its regular JAs that enhance it are only useful in situations where other people's buffs don't already have you covered.
That leaves Savagery Warcry, Blood Rage, Tomahawk, and Retaliation as its stand outs. Retaliation doesn't work on boss autos that are considered WSes. Tomahawk's timer and single target nature keeps it quite limited. Blood Rage is still in its nerfed state, and is kind of just a gap filler JA. Savagery Warcry is amazing.
Can't cap your own delay reduction in Fencer build. Hasso from /sam also technically leaves you about 1% under cap for 2-handers. Dual Wield you can cap on your own with /nin or /dnc, but Dual Wield builds are mostly meme worthy for WAR. Meanwhile, DRK, SAM, DRG, NIN, DNC, MNK, PUP, THF, BLU, COR, and RNG can all cap the delay reduction of their primary methods of attack without things from outside themselves (most of them without subjobs even).
Maybe I'm being a bit hyperbolic, but it just seems like WAR is being held back.
