This is an area that I bring all of my characters too at round 28 and hang around till at least 30
the area is called Dun Garok Thottbot World of Warcraft: Map: Dun Garok Rifleman in Hillsbrad Foothills
The area is filled with alliance friendly dwarves so if you are on a pvp server you will most likely be left alone here (not sure if allies have any quest givers here).
This area used to be elite pre 2.3 and the Dun Garok riflemen CAN drop a very nice leather helm for twinks/semi-twinks Thottbot World of Warcraft: Humbert's Helm
The drop rate is around 0.5% but grinding the area will net you money drops and silk cloth for selling on the AH, the helm may also be sold on neutral AH's for even more money, ranges from 20-50g on my server
Also the Dun Garok priests in the little area for some reason give 200 more exp than the other dun garok mobs 380+ instead of 180+
Anyways, I know this isnt much but it is my attempt at starting to contribute
Thank You
