A great addition to the universe of Warcraft
Burning Crusade is the first expansion of the franchise of World of Warcraft and by far is the best expansion of this game.
The game sets you in Outlands or also known as Draenor the original homeworld of the orcs and you will travel through different places like Hellfire Peninsula, Nagrand, Netherstorm and other places. Also you will see great views and how Nerzhul left the planet after he opened the dimensional gates fleeing from the angry alliance.
This expansion also introduces two new races, the draenei for the alliance and the blood elves for the horde with four new introductory areas plus the Isle of Quel'Danas, home to the destroyed Sunwell.
The end content of the game is great, you will raid places like Karazhan the tower of Medivh, Tempest Keep, seat of Prince Kael or even the Black Temple where you will have an epic fight with the traitor Illidan, also you will see places set in the past thanks to the caverns of time.
The new profession that is Jewelcrafting is fantastic, it boost certain pieces of gear that have sockets and also you can make rings and necklaces.
The only bad thing of the expansion is the pvp, the only way for get gear now is by arenas and not by battlegrounds and they only added one that is a combination of two old battlegrounds and with the classes imbalances it is hard to win matches if any of the overpowered classes are there (and usually are there).
Again like Vanilla WoW all the game content of this expansion is dead so don't expect to find easily groups for raid this game content but if you can you will see why this expansion will be the best.
