Some people like it better... maybe have vast user libraries of marked locations.
At one time, prior to the changing wood/ore spawns, I had the entire Destard Mountain mapped for ore, including the dungeon. Every mining spot had the correct color of ore that spawned there.
I also had every LJ spot from the Maze, south to the Mountain marked for wood types.
I'd guess there are some free shards that don't rotate resource spawn.... this might benefit them.
