Yeah sorry about that but Its for the sake of RP, check out the scarlet crusade tabard and try to figure out why I attack undead :P (or any other horde for that matter cause you are allies with undead) only ones getting away alive are Blood Elves wearing the Scarlet Crusade Tabard, You'll probably get a salute or hug then.
Edit:
forgot to quote but this is refering to what krageth (or kargeth...man I suck at remembering names) posted earlier, scroll up :P
