The problem about those levels is that you are starting yo get strong but your hit points are still low, so you need to watch out whre where you rush.
You could actualy do quité actually do quite good exp and not high waste in wintercourts main floor and -1, using fire ( one stays on the fire throwing acá, aca, and the other one lures running around)
Glooth bandits east is a forgotten place, where you can still do easily 1kk+/h without waste.
Mini-roshamuul of feirist would be also a nice place for you, if the ms helps the RP to heal with uh if he gets 'big' lures.
Oramond west is a cool place too yo exp, but the loot is mostly bad.
Lizard city or lizard chosen are also good respawns, but I al not sure about the exp rp-ms.
Hope I helped :]
