imo SE doesn’t need to reduce the light needed as much as increase the light various mobs give. Theres 2 good places to farm dragons and 3 places to farm anubys. If those are taken you’re stuck hopping instances or hoping one of the groups in a good area chases a NM and you/your group take it when they leave (aaand hope they let you be when they return). While some people would inevitably still fight over the best spots, alternative monsters to farm would at least give other highlv groups something to grind.
