This is one of my little pet peeves with the game and mob distribution. It's not a huge deal having mobs get more difficult further away from the cities for me but I find it extremely annoying that mob levels seem all over the place making grind spots more difficult than they should be to find.

What I would like is just all mobs in the area to be roughly around the same level so they would all be viable grinding options. So if I go to Camp Horizon all mobs in the camps surrounding area should be around rank 20/25. If I go to Broken Water they should all be around R40/45. If I go to grind Raptors and mobs near or around them should be around the same level so they provide more options of things to kill during a grind party so you don't have to solely focus on Raptors.
