Stun Jamadhar +1 oddity

[Mazon]

Has anyone else noticed this oddity for the Hand-to-Hand weapon Stun Jamadhar and it's HQ version:

Stun Jamadhar
Level: 66
Slot: Weapon
Type: Hand-to-Hand: Katar
Jobs: DRK MNK PUP RDM WAR
Races: All
Damage: +15
Delay: +84
TP Per Hit: 4.2%

Stun Jamadhar +1
Level: 66
Slot: Weapon
Type: Hand-to-Hand: Katar
Jobs: DRK NIN THF
Races: All
Damage: +16
Delay: +75
TP Per Hit: 4.1%

How does a weapon change the job classes that can equip it, through HQ? Did anyone else notice this?

I know in the beginning there were a lot of Hand to Hand weapons monks couldn't use, mostly weapons with added effects. I'm not aware of them changing it though. I haven't checked in a while.

I suppose the +1 version could have slipped past the interns.

I'll chalk it up to a blunder. It just caught my attention as I was browsing the AH in Jeuno.

I'd buy a pair just to mess around/skillup with if not for the thought that it might get rectified.

There are a few items that go the other way, opening up to more classes with the HQ.

Coeurl Jerkin
Level: 70
Slot: Body
Type: Armor: Leather
Jobs: BST RNG THF
Defense: 42
HP -1%
Accuracy +3
Evasion +2

Torama Jerkin
Level: 70
Slot: Body
Type: Armor: Leather
Jobs: BST RDM RNG THF
Defense: 43
HP -1%
Accuracy +4
Evasion +3

I think it's an odd design decision rather than an oversight or mistake. It might actually be kindof interesting for crafters if more items had narrower HQs, giving the NQ a distinctly different market than the HQ.
