This one's a doozy, adding new dungeons, raids and a new feature that makes raid groups easier to find. And, of course, you'll finally fight Deathwing.
If you're the type of player that's logged into 'WoW' on a daily basis, you already know, but for those that have lapsed in their habit, there's a new patch out that brings some fairly big things to Azeroth.
First and foremost, there are new dungeons and a new raid called Dragon Soul. Groups of 10 and 25 will fight through this dungeon until they reach the final encounter - Deathwing. As you might imagine, the gear dropped reflects the difficulty of the task.
If you're not in a high end raiding guild, Blizzard has your back. The new Raid Finder feature operates much like the Dungeon Finder and sets you up with a balanced group to take on these monstrous challenges. Difficulty is scaled down as is loot, but if you want to experience Dragon Soul and take out Deathwing, the Raid Finder will help you do it.
One other feature that's certain to make old-school players happy is Transmogrification, which allows you to make your new gear look like your old gear. No longer will you have to decide between style and stats - you can have both in one.
Of course, there's a lot more to the patch than can be summed up here, so hit up Blizzard for the official notes.
