Another incredibly common complaint and wish from the community is restoring players to the content they purchased. The Dark Below granted me access to higher level strikes and crucible gaming modes which are still available to players at a lower light level, but not a player who has not purchased TTK. Have separate playlists with year 1 gear for year 1 players. It's what every other MMO does, they don't lock out players who buy their content from using said content when those same people decide not to purchase other content, because if they do they will not purchase ANY future content.
