First i have no access to elite so if posted there not my fault.
On with the exploit I'm fighting Aiki the chosen atm if i queue for a bg (specific haven't tested random) and i beat her down while boosting a carry pet, i dont finish the fight i wait till queue pops kill whiskers then as my carry pet steps forward to receive the exp i instantly join the bg aiki's quest doesn't complete i do bg zone back out rinse repeat. No special tool used (EU)
