Seconded on party, but if you`re dead set on soloing, make sure you have sigil, /dnc, and try bats just inside Oztroja (S). Both singles and bat trios are 70-72, zone is close. I'm not entirely sure there are enough pops to actually kill the bats, but you can take them down to 30% or so then zone them (<25% they TP at 100%, and while they don't have devastating WS there is no reason to force it). Depop anything T, and grab all the DC's you can while you're still under the level 70 skillcap.
Also remember you're not there to deal awesome damage - turtle up a bit with arhat's gear, evasion, etc. You don't even need to use a weapon, you'll hit faster ( => more skillup chances) and lighter (nice EM mobs last longer) without one.

"You sir are a liar. Blackmages get to fight anything thats at least 3 times my size ingame too."
"I still don't get it. Where do you find these gargantuan colibri, and why would you want to merit off of one?"
