Bungie, If much of the terrain we can see is playable terrain, what's the harm in pulling down some of the invisible walls and kill volume when you leave your designated area? You could simply RNG the appropriate mobs in those areas at level 24-30. Material spawns seem simple enough. Just let us roam. The playable area could be doubled with tweaks that you claimed were already in the system. Tear down some walls Bungie.
