After unveiling the "World of Warcraft: Legion" Patch 7.1 several weeks ago, Blizzard officially announced the upcoming content of two new patches during BlizzCon 2016, which happened over the weekend.

The first set of new content will come out under Patch 7.1.5, which is considered as the smaller one among the two.

According to the game developer, Patch 7.1.5 will come out with several additions, including all the six dungeons from the "World of Warcraft: Mists of Pandaria" expansion that first came out in 2012. It will also feature the return of the Brawler's Guild, which will feature a number of new bosses, as well as brand-new "raid" challenges to attract other players lurking in the arena.

The Patch 7.1.5 will also bring "micro-holidays" into the game, which will be composed of mini-events that will normally last for one day or two to add more challenges to the game. These "micro-holidays" will be held at different times.

Meanwhile, Patch 7.2 could be considered to come out with a major content called "The Tomb of Sargeras." It will feature a new raid, the Class Order Campaign continuation, and a new set of achievements, among others

One of the contents of Patch 7.2 will bring players back to the Broken Shore to continue their Class Order Campaign. According to the statement on the game's official website, "Players will take part in helping build the Legionfall base to establish the initial foothold on the island, then work their way through the Legion's defenses and eventually reach the stronghold."

On the other hand, the Tomb of Sargeras will be waiting for the players on the opposite side of the Broken Shore. The raid dungeon, which is formerly known as the Temple of Elune, will feature nine new bosses that should be defeated.

A new dungeon called the Cathedral of Eternal Night will also be released with the upcoming Patch 7.2. New PvP Brawls will also be introduced.

Blizzard did not reveal the exact release dates of both patches, but Patch 7.2 is expected to come out immediately after Patch 7.1.5.
