This is probably common knowledge, but the Skyguard and Ogril'la encampments are easy picking for cheap honor.
1. Find an enemy player in one of these settlements. Normally the guards would rape you inside out, but that's not the case anymore. (note: AFK people work better, just since no witnesses = no report)
2. Stand on top of a house/tent. Those weird ribcage ones for skyguard work fine, as well as the huge tree limb above the questgiver, and in Ogril'la, I've tried the huge tent thing near the quartermaster. Try the rest at your own risk, verification is always a plus.
3. Pwn your target.
The guards cant path up the buildings, and dont have ranged attacks, so you won't get killed. Enjoy your honor farming.
