*****EDIT***** Alliance only!
In the instance Shadow Fang Keep in Silver Pine Forest (lvl 20+ ish) there is a mob that respawns instantly after you kill him.
When you first zone in you will notice a gate in front of you with argul, whom will kill a undead character then teleport off. The undead guy he kills is your target. Clear to him (takes about 1 minute on a 60) and stand there and beat the crap out of him untillyou're 300 in all your weapon skills. He hardly does any damage so you can stand there for a long time, if not forever.
Enjoy
