I do a lap around Udgaard. If you're lucky someone killed Thestur for a wand so there may be flail/bracers/shield etc laying around. Then I run to ar'atouldain for black iron gear. After that, if past lvl 11, I run to Kiadana and hope that someone has gone through the inner areas there. Those are my three main go-tos.
I'll also check the who list. If I see people who might be leveling underwater I'll run down ruins of the deep in hopes of getting a sword from the spirits or spear from the sahuagin. (spear is avg 25, sword is avg 18.)
If the uptime is high I may run down to the underdark. But people don't clear patrollers and all out like they used to. Uh. I may edit this post more as more come to me. I'm all about the gear scavenge.
