I know someone who did 59 as a necro at the giant fort in Burning Woods...don't do that, you'll be lucky to get 2% a session.
I bit the bullet on mine, organized some guild groups for Sebilis and did a 14 hour marathon in crypt with some random guys with a charmed pet (people bitch about necro dps, but they soon hush their gums when you've got a necro/enchanter combo destroying everything with 2 charmed pets)

If you go that route, always say in your LFG that you're happy to charm an undead pet. If you get a group for another camp, go down to the crypt door assuming it's clear and just stand at it... a roamer will either attack immediately or will move up to you through the door. Charm that and you're in for a good session <3
Or there's HS...no bad place to be but the basement is slow at 59. Consider a duo/trio, take a wing and things should be ez pz.
