I think it was a poor move to bring back the exact same location on the moon for Shadowkeep.
It should have been on the dark side of the moon.
If bungie really wanted to blow people away for new light they would have implemented D1 into D2. Take ownership of the MMO vision for the game and give PC players the D1 experience.
Imagine playing through all of D1 + DLCs [u]and then[/u] D2: Red War story not only unlocks around 4 new expansive locations for the player to explore but also revamps previously existing areas in D1 like Venus. Warmind would have added a new location to an already existing world.
Imagine if they had both "Dark Delow" & "Shadowkeep" as locations that players unlock over the course of the story.
