1. Get 3 other level 90s that can get through Tol' Vir starting area wall (note only 1 side works). These classes can be a mage (blink), Druid (blink), Warrior (Charge / Friendly charge), Priest (sybo druid he then grips you through) and last off all you can polly all classes through that can take up to a few min to get it right. Just do a 2vs2 war game.
2. Now all you guys are out run as a group just away from the arena it deosnt matter what way (north takes you to old AQ btw will update screen shots of that). Now you run until the other arena players are now friendly and you will then be able to trade / duel can't wisper though only real id wisper. You will not die in duels.
3. Yet to test but you should be able to trade cross faction, please note that cross realm won't work. NOTE we have got an mc idea that will work if this isnt working.
4. You can duel and duel players from the opposite team no matter the faction.
