Every expansion comes with a special tie-in event during the pre-patch, allowing players to farm fun rewards and gear up alts easily. This recent Dragonflight beta update adds some ilvl 280 catch-up loot from proto-dragon bosses, suggesting it will be part of a pre-launch event.
The ancient proto-dragons, harnessing elemental power, will be one of the main antagonists leading up to the Vault of the Incarnates raid, so it makes sense we’d see them attacking in the pre-patch.
