The Deathwing raid encounter has been announced. "DRAGONSOUL" will bring the long awaited Deathwing encounter which will only drop weapons and of course a rare mount. Along with Deathwing there will be 6 other boss encounters. Along with the patch there will be 3 new 5-mans that will build up the lore a little bit however it will be lore that involves some time-travel which some don't care for but we will just have to see how it all plays out.
Blizzard has also announced a melee buff coming up in order to compete with randged damage. And rogues are excited as we now know the legendary weapon drops from Deathwing will be a pair.
4.3 looks to bring even more updates so check out the video for all these and more.
