Anyone have any good outdoors AoE locations?

Stonetalon Mountains, Windshear Crag Mine - 20-22 mobs, ~85% melee - This location is good for lvl 20-27. Can pull 5-20 mobs in each pull, doing loops going in at one entrance and out the other entrance and then back in the first entrance, after clearing it ~50-75% mobs respawn on the next lap.
Mobs drop ~70% wool cloth, 25% linen cloth, 5% silk cloth (just a guess).
XP per hour ~15k.
