Sorry for my bad English. It isn't my native language.
There is a new forsaken quest A Daughter's Embrace , where you should escort Lilian to the Crusader's Run
She has a ability that instantly kills any Scarlet mob at this area, so all you need to do is hit the mob and wait until she kills him (you get 100% Exp for that kill). I was able to get a level within 7-10 minutes as a warrior. If more than 3 mobs near Lilian, she instantly kill them all and you do not get experience.
Quest is part of the chain.
Once again I apologize for my English.
