Stop what your doing and faction change or reroll a new character to horde. Everyone. Drop the ego and nostalgia if your hung up on your alliance. It's over for that faction. With dungeons and lfr and normal raiding arguably obsolete due to titan forging of lower ilevel stuff the only thing left is pvp. And if you wanna even have a chance in pvp you need to be horde. Do it. Trust me. It will be such a weight off your shoulders.
