is there a mod that detects chests like npcscan or something?
I don't use addons myself but from what I heard a gold-making site is working on one.
Yay.
A note on the Hillsbarad map: thank you.
For the squishier Alliance toons: you can restrict yourself to 3, 4, and 6, there are no Hostile mobs there (Stormpike and SI:7). 5 sometimes co-spawns with Jimmy the Bleeder, if not it's free for the taking as well. The mobs near/in the Dalaran crater (1) aren't Hostile to Alliance either but you have to cross an area with a smattering of spiders and bears. As far as I know the Chests at 1 never spawn inside one of the buildings with a roof or the tower, if anybody knows if they do that would be great.
It takes about 6 minutes to ride this parcours, at least if you kille the Rares on general principle (or 'mog skins; Jimmy drops Cloth as well.), the AV Vendor Repairs, and there is a Forge to Smelt teh overly-abundant Ore in the region at the 4/5 hill. Have Looted close to 40 chests now, about 75% required 21+, 20% were rakzur clubs and other now near-useless level 16-18 goodies, 5% level 20's though sadly no Mantle as of yet.
I'd recommend Dun Modr in the Wetlands for the stronger/Hit capped types, the Dark Irons drop plenty of Cloth and consumables, and the place is a veritable ghost-town as far as players are concerned (Hillsbarad being one of the more popular Horde Questing areas, the same reason why Duskwood wasn't really working for me; the abundance of Ally-friendly mobs in the Hills keeps Hordies away).
