Necro lvl 17 - when to leave Kurns?

[Dragnath]

I found the SK mobs were usually contested, WW giants the best xp for me from 22-29. The cougars in Iceclad are good xp starting at 29, but their loot is pretty bad. I leveled 29-35 at Misty guards, there is enough of them that you can generally find one or two open to kill and the loot is good. Bored of the guards now and looking for alternatives for 35+.
