I took my Shamen up there to do the Southshore yeti fur quest + nearby ogres at the same time as I did the Greench quest...plenty of horde around, none bothered me, a few of the lowbies ran in fear(I lol'd despite making no aggressive action, just questing) though I did get the killing blow from twin-shocks on a guy named Jeenyus who was being ganked anyways, and was a total dick to my rogue while I was still lvling him in outland ;p
