Hey there!
(Just searched for "Healing with roses" and "Alliance Herb Pouch", but the search didn't bring anything up. So maybe I'm just, blind. Excuse me for reposting something I haven't read anyways. :P )
Farming in Wintergrasp I just discovered something:
The daylie-quest in Wintergrasp Healing with Roses clearly states that you should get the "Alliance Herb Pouches" (Horde side ofc) from "Alliance Palyers" in the region of the Steppe of Life in southwestern Wintergrasp.
I just went there to farm for Crystalized Life and stumbled upon one of these pouches in one of the Living Lashers there.
They have a droprate of about 10-25% but farming Lvl80 Mobs with 12k health is just faster and easier than waiting for Season 4-6 equipped Alliance Players with Tenacity to show up and kill
So enjoy your bonus Honor, 3 Stonekeepers Shards and 13g (@ 80) every day for a PvP-Daylie that can be done Pve-style.
[Edit]: Ewwwwwwwww... fail. Nevermind. The questtext states that the Lashers "may" have some too. Delete please!!!
/facepalm
