What you Need:
2 WoW Accounts
1 horde and 1 Alliance on the same server- Both around the same level (2 70's preferably)
OK....
First set WoW up in windowed mode so you can efficiently duel screen
Get on Both your horde and alliance character and DIE NEAT GRAVEYARD ON ONE OF THEM
Get on your other character that you want honor on and go to the graveyard where the other character is now at - WITHOUT REZ SICKNESS OR IT WILL NOT WORK
Kill your other player, get honor
RESSURECT WITHOUT SPIRIT HEALER...
REPEAT
I did this for 3 hours the other day and got quite a bit of honor from it--
MUST BE in contested territory or have both toons PvP flagged
