Ive been leveling 10 characters at once because i look at it like im going to have to do the quests again anyways if i were to run 5 guys twice but anywho the questing is just killer man. i have to keep myself interested by wiping out every hordie in sight every now and then. However i have gotten 2 levels in 2 days so i aint complaining too much. the jade forest is definitely the worst area ive encountered so far. once you go to valley of four winds its not as bad imo
