Blizzard is leveraging pure nostalgia with WoW Remix: Mists of Pandaria, a limited-time opportunity to rewind time and play through a modernized version of the 2011 expansion. When it goes live on May 16, you'll be able to quickly level up a character who will transfer over to the regular servers when it's over, presumably as a fun way to prepare for The War Within expansion later this year.
WoW expansions are already playable as you level up in WoW, but WoW Remix: Mists of Pandaria will take place on separate servers and feature faster leveling, new items, and rewards to take back to the regular MMO. Think of it like an accelerated tour through one of WoW's best expansions, an alternative to the normal leveling experience.
