I know no one from the Overwatch team will read this, but It could work.

Archives will be the only event to change every year (New Name,New comic, New Lore, New area, or Reused area, but changed). We get to keep both Uprising and Retribution PvE mode without the Event. The event isn’t the pve, but the Skins and emote etc Itself. The Items will lock like always after the event. Also It would be a great place to practice unlike the training range. You could make a tab under “Overwatch League” called “Overwatch Archives”.
