Leatherworking on PTR 2.3

On patch 2.3's PTR, there are a few new pattern for leatherworking. Hunters can finally get rid of their level 35 quiver or ammo pouch without grinding Consortium or Kurenai/Mag'har reputations.

Knothide Ammo Pouch (20 Slot)
Equip: Increase ranged attack speed by 15%
24x Knothide Leather, 1x Primal Air, 4x Rune Thread

Knothide Quiver (20 Slot)
Equip: Increase ranged attack speed by 15%
20x Knothide Leather, 30x Arakkoa Feather, 2x Rune Thread

Netherscale Ammo Pouch (24 Slot)
Equip: Increase ranged attack speed by 15%
12x Heavy Knothide Leather, 40x Nether Dragonscales, 12x Primal Earth, 1x Primal Nether

Quiver of a Thousand Feathers (24 Slot)
Equip: Increase ranged attack speed by 15%
8x Heavy Knothide Leather, 99x Light Feather, 2x Primal Air, 1x Primal Nether

The 24-slot seems to require a rather insane amount of rare items. It also seems to me that the mats for quivers less uncommon than for ammo pouches. Who would have kept Arakkoa feathers after getting honored from Lower City? While 99 light feathers are easy to grind from Westfall, 20 nether dragonscales are comparatively hard to get by.

Apart from these hunter items, there are two new armor kit patterns as well.

Heavy Knothide Armor Kit
Permanently increase the stamina of an item worm on head, chest, shoulders, legs, hands or feet by 10.
3x Heavy Knothide Leather

Glove Reinforcements
Permanently increase the armor on a pair of gloves by 240.
18x Heavy Knothide Leather, 14x Primal Earth, 1x Rune Thread

Note that Heavy Knothide Armor kit can be put on head and shoulders. (^_^)
Would other armor kits be also allowed to put on head and shoulders later? Though it might not be a big hit for most armor kits since the glyph and inscriptions are by far better, it would be a big boost for the resistant armor kit.
The glove 240-armor enchant is not very exciting since agility or threat would probably be better. Still it is a nice option to give different options for an enchant and a function (or financial support) for leatherworker.

Someone also found a leatherworking bag pattern, oh now I got that from a trainer for 1g20s.
Edited: Oh, did I forget about the drums? The world drop drums patterns (restoration and speed) are now available when revered with Kurenai/Mag'har. The cast time for drums of restoration, speed, battle and war are removed. See details for all professions.
