No one is losing their minds over it. The Cataclysm was shoved down our throats during leveling. Teldrassil which is a vital plot point and Horde warcrime, seemingly vanished from the sight of players. I'd like to believe Blizzard did this just to make leveling easier and non-story dependant since Kul Tiras and Zandalar mostly have their own contained stories, although the bitterness in me wants to believe they are sweeping it under the rug.
