This quality of life change would not affect the economy nor the balance. It will just save some time and reduces frustration and time you are not playing.
I have seen it working on another server and it is just awesome. It reduces the annoying search for the correct target in the correct direction.
When you want to accept a mission, right now the direction is random. There is a possibility to remove the rng and add the direction of the player. For example: If the player is looking towards west, only missions to the west would be displayed.
More love for Missions!
