Ok I'll share my favorite classic camp spot since I'm not playing here. It is always open, and has endless dark blue mobs, very few light blue. No trains, no drama, most people won't even know you're there. The perfect place to grind in peace 40ish-50
I call it sword #2. No one ever seemed to go there, ever, so I feel it's worthy to mention here.
Go to hole. Go to slab, keep going to docks, keep going past docks at the area right before you turn in to the docs gate, two rooms over you'll find a second camp with a sword in the ground. Camp right there and pull from the surrounding buildings. Some of the buildings have like 20+ mobs, mostly dark blue (golems), very little light blue trash.
You can get there from zone in, or from jumping in the pit. You can also make a quick trip from camp down the tunnel to undead and grab an undead pet if you wish. A correct level golem charm will be basically just as good though and less hassle/movement.
Also, one of the buildings right off of "sword #2" has a room in the back with zero spawns. A perfect safe room to camp in, and just pick back up grinding when you log on again
