The only use that's popping into my mind is KClub RNG.
Most jobs are more than capped on accuracy, regardless of weapon rating, both inside and outside of Abyssea. It's a good transition piece, but not a must have.
Seeing as DNC in full AF+2 can reach 25% haste without body this seems pretty useful for DNC. if you're willing to sacrifice 1% haste can have +54 store tp through gear alone.
Great ACC piece for Mnk. 9 more acc and 20 more def than Usukane body, and Mnk is generally capped on fStr so Usukane's 8 str is doing almost nothing.
Definitely opens up a lot of options for any job that can use it.
