Just to help out anyone who is thinking about lvling on these. I usually steer clear of them almost entirely in La Theine and instead fight the worms that spawn from lvl9 til aorund lvl 12. At lvl 12 you can head to Valkrum to fight Lizards (possibly as early as lvl 10, but the solong on the worms is really good and you have no worries about finding an experienced pt. :)) Then just move on to Snips in Valkrum at around lvl 14-15. Beware the gobs!!
at lvl15 you should be fighting clippers or damselflies(if its a great party) in valkurm. i usually solo on worms/sheep in latheine until lvl14(i cant stand valkurm n00bs).
at lvl15 those will con easy prey, or low decent challenge, and the exp will suck, whereas in valkurm you can pull 100+ per mob
I'm a level 13 warrior, and I'm taking mad sheep solo. There is also **** like Goblin Tinkerers in this area that will kick a level 13 warrior's ***, so soloing in this area is still a reasonable idea.
