With Remix: Mists of Pandaria, players will be able to relive the whole Pandaria expansion, including the iconic Mists of Pandaria raids, including Heroic mode raids.
Players will only need a WoW subscription to fully participate in this event, similar to Plunderstorm.
If you don't have a subscription, you can still participate in the early stages of it, limited to level 20.
Note that this isn't Mists of Pandaria Classic, so you will be using Dragonflight's class design and abilities, which the event's features will enhance.
