I'm kind of stuck at 52 at the moment. Waiting for others to catch up, but also searching for a good area to fight. Dragon Necropolis is alright, with a group. As a monk with fairly good DPS, it takes a while to kill anything more than the Lost Ones. Which presents a problem as the Lost Ones go light blue at 54. If you don't have at least three people, I'd say it's pointless to try DN. However, on the plus side, there's normally people LFG in there.
