I normally went there, on the beach.
and killed Langk Lizardman Lieutenants and also some eyes i think (not sure about the eves tho xD)
The Langk Lizardman Lieutenants are level 22, but lately I've seen some other bot parties there...
Then...yee you can go Cruma and kill Mist Leeches, Horror mist Rippers (aggro) and Gray Ants (Mobs are level 25-27), then go west and kill Marsh Stakato Workers, Stinger Wasps (aggro) and Toad Lords (Mobs about level 30), then either go to Heine (next paragraph) or go north and kill Marsh Stakato Soldiers, Marsh Stakato Drones (aggro) and Marsh Spiders (aggro) (Mobs are about level 34)... well but there are some players in cruma swamp.
After that go to Heine, Start at field of Silence and kill Dread Wolves (level 35, aggro), they have 1/2 hp but there are plenty. For harder mobs, just go in southern direction. There are spots in Field of Silence and Field of Whispers where I haven't seen other players for days.
