I think you are missing the overall design philosophy that bungie is using for the raid the game in general. Their philosophy seems to create intended player behaviors and intended us of mechanics (limiting the depth of how you can use those mechanics). Were it may actually behoove them use a design philosophy where they just give players tools to complete challenges and puzzles put infront of players and view all solutions created by those tools as intended barring malfunctioning code. As the latter creates more acceptable depth and exploration of game mechanics where as the former dissuades players from exploring the depth of the game mechanic in fear the depth is not intended.
