Low levels shouldn't be camping at icepoint if they want to get northern NM's. At the least if they are going to camp they should be at or around Igloo given it puts them north and well within reach of both East and West NM's when they spawn. That camp spot is good when you have a return handy for low level spawns. If you have no return I would recommend camping the small elevated area just above the Northern bunny fate given there is a shortcut drop down to low level areas there.

People are just not going to wait for low levels to run up North for fate pops.
