Hello! Today i found a great way to get your unarmed skill high!
1. Complete the quest The Torch of Retribution - Quests - World of Warcraft
Then you will get Torch of Retribution - Items - World of Warcraft
2.Go to any place with low lvl enemys. (I only tested this on the deeprun tram rats)
3. Equip Torch of retribution and start attacking an enemy. Your character will be attacking unarmed but every hit it will say "immune" that means you can just auto-attack untill you get full skill without killing the enemy!
I only tested these on the deeprun tram rats, so im not sure if it works anywhere else.
