Leveling for Duo's

[maultar]

Sometimes the MRS. and I like to duo, out of the way of trains, in some quiet corner nobody likes to go to. At level 38/39 Is there such a place? We prefer dungeons for bonus exp. Problem is we are finding that any mobs that are casters nuke hard and she heals more with more downtime. Or mob healers can be a pain too. In paw the Nich mobs nuke hard and heal. Not even sure what class that is. Someone suggestex mm castle ent or pits. Are those mostly melee mobs? Would kedge shark area be good? Or the seahorses by undertow? Think that area was called the great hall. Or are we doomed to group it out in sol b until 50?
