Samwise Didier as an April Fools style joke—were later reintroduced to the Warcraft canon in the bonus Horde campaign of Warcraft III: The Frozen Throne. Unlike previous races in World of Warcraft, which are tied to either the Horde or Alliance in-game factions, pandaren are faction-neutral for the early levels of the game. Until the end of the principal quest line on the Wandering Isle, the pandaren player character is faction-less; at the end of their starting experience, the player chooses to align with either the Horde or the Alliance. The pandaren speak both the pandaren language (though the factional language barrier will still remain between Horde and Alliance pandaren) and the main languages of their faction, which are Common (Alliance) and Orcish (Horde).

Challenge Modes Mists of Pandaria introduced Challenge Modes, a gameplay option where a dungeon group is challenged to finish a dungeon of increased difficulty as quickly as possible. All players' gear is normalized, allowing for fair ranking. Depending on how quickly the group clears the dungeon, the group will earn one of three possible medals. The higher the medal quality, the higher the prize for achieving that medal. Pet Battle System Introduced with the expansion, the pet battle system allows non-combat vanity pets to be pitted in battle against each other in a turn-based combat system, either against wild pets or other players' pets. Defeating wild pets allows players to capture them, adding to their collection and their pet journal. Pets can be trained up to a maximum level of 25, with new abilities and enhanced
