I do mourn the death of OG Blizz. Warcraft 3, StarCraft, and Diablo 2 were a huge part of my childhood gaming experience. Even OG WoW, though what made it magical was mostly the friends made along the way.
But that Blizz died a looooong time ago. Started sometime around Mists of Pandaria, and the tombstone was set around the time Diablo 3 came out.
