Quote from: Blizzard
Mark your calendar for 20 March when the 10.2.6 content update goes live with a bold, new, limited-time event. You won’t want to miss out on the fun. It’s important to note that Dragonflight season 4 will go live several weeks after the release of the 10.2.6 content update. For heroes working toward the Amirdrassil Feats of Strength, you’ll need to obtain Ahead of the Curve: Fyrakk the Blazing before Season 4 begins, and the achievement is no longer available to earn.
