The World of Warcraft Mists of Pandaria Remix player base is divided between those who play the game the regular way (Non-Froggers) and those who use speed-leveling and farming methods to play more efficiently (Frog Men).
When WoW‘s MoP Remix came out, the idea was to let the player experience and re-experience WoW’s fifth expansion (which originally came out in 2012) in a slightly accelerated way while also getting a chance to win some rare loot.
