My leveling experience (currently 55 DEF SK): I did 52 and 53 in Eastern Wastes at the GD zoneline. You can pull frost giants, manticores, etc. all dark blue, into the tunnel leading to GD, and fear kite with no risk of adds, or mob running too far. Get him in your kill tunnel, kill sit pull another, repeat. Frost giant beards, SS and Thurg faction, heads toes weapons, and coin isn't awful.
then 54 in Everfrost killing barbarian guards #5 on the map in Everfrost Peaks, you can bank in Qeynos underground (just can't buy drink
