The largest addition to World of Warcraft in the 4.3 patch is a Deathwing raid. The raid will feature multiple phases including flying in the sky. The raid will be for high level players and, according to Blizzard, it will be "super epic".
The 4.3 patch will also add the transmogrifying feature, allowing higher tier armour to be reskinned to look like any lower tier.
Blizzard said that the feature will give players more customisation options for their character's appearance, without sacrificing stats from better equipment.
The third addition from the 4.3 patch will be Void Storage. For a fee, players will be able to store items in the Void Storage and move items between Void Storage and their banks. In many ways, Void Storage is similar to a second bank for players.
4.3 will also add a Raid Finder to act as a matchmaking tool for players to build raid groups more easily. The Raid Finder will work with raids of up to 25 players.
