In the explanation of what is the irminsul and how it work, it would be a good idea for Hoyoverse to put the previous events that have plot (such as unreconciled stars, albedos events, the festival events, gaa, etc) as memories scattered around teyvat in their respective areas, like have them as the character chapters, but without the shops and coop/single player reward games, just the story element, so players who didn’t have the chance can play and see what they missed out on.

For big things like the GAA have memory ley lines when they have a new event involving the archipelago (these should have a couple of common chest, not more than 10 per island and their side missions/main mission, in the domains of these instead of chests have the enemies have their drop items), same thing with the festival events, have ley lines activate after the end of the festival of that update
