Okay this place is great to get your weapon skill up from 1-300.
On Quel'Danas (the new island) there are far in the south a whole bunch of undead mob.
The ghuls hit you for like 1-20 dmg but have health like normal lvl 70 mobs. You could just buy a health-reg item at the auction house or, even better, just buy a cheap troll-blood potion. It will be enough to keep you alive.
Just pull one of the ghuls, search a quite corner and try to hit him till he is dead, which will take a while if you lvl the whole way from 1-350.
If you get near 350, like 330 for example, and they die to quick just buy a cheap grey lvl 1 weapon.
For 1-300 one mob should be enough and you can just go afk. After that you maybe need to get new victims after a short while like 5 minutes.
Hint: don't try the skeletons, they hit for much more (30-100 lol)
