Dragonflight is set to be the shortest expansion in WoWs history
While it certainly doesn't feel that way, due to all of the content we've gotten in Dragonflight, I started to think about it, then did a little math, and yes Dragonflight at 633 days, beats out the former shortest expansion WoD (656days) by 23 days, and Cataclysm (658days). Dragonflight is a full 199 days shorter than BFA, the longest expansion, that's over six and a half months.
