Another fast weapon lvling spot, but this time in Kalimdor
Run to the farm in Durotar. You can see the place here on the map, coords are underneath if you would need them.
There are normally more pigs, but I killed them first with consecration (first pally, had to try it out :P). I noticed this one stayed alive, and I could hack it as much as I liked and he didn't die. Have fun :P
