Unity is fine, but some of the newer jobs can't wear much or any of the rehashed equipment. It looks like the next update will see the re-release of several pieces of near-JSE. For instance:
Vampire Earring - WAR/PLD/DRK/BST/SAM/NIN
Vampiric Cloak - DRK
Tredecim Scythe - DRK
Cure Clogs - WHM
Caitliff's Socks - many jobs
Hercules' Ring - WAR/PLD
Perseus's Harpe* - WAR/THF
Zoolater Hat* - BST
Bandomusha Kote* - MNK/SAM/NIN
* They're probably going to pick 2 out of these 3 pieces because every Unity NM so far has only had 2 drops.
I'm going to toss in one more just for fun:
Jugo Kukri - THF
DNC, BLU, COR are left off most or all this gear because they were released after it and SE didn't include them on most JSE. Dancer, in particular, lacked any reasonable level 75 daggers for this reason and was left chasing weird, inconvenient weapons like Papilio Kirpan and Cinquedea that were added long after the job's release. Please don't do that to us again.
