In the past, dungeons have been seen as a stepping stone to raids. If you stopped there, so be it, but the goal was generally to get past them and get on to bigger things. With challenge modes now in game, it may be that 5-man groups will be seen as a pinnacle of end game activity.
With that in mind, getting the good gear out of these dungeons may be more important than ever. This week, we'll take a look at heroic dungeon drops. For the most part, in comparing these pieces, we will be focused on getting parry and dodge for tanks, critical strike and haste for unholy and two-hand frost, and haste and mastery for dual wield frost. Note, of course, that you still want to get 7.5% hit and expertise each as DPS, so that may override other gear choices at time.
Note that Scenarios will also have a chance to drop an item level 463 item, so if you do Scenarios, keep an eye out for those. However, since they are all items with randomly generated prefixes, it's difficult to preview them in a gear list, so just know they exist.
