If you're frequenting any of the rogue community sites, you've seen the question: Should I be using No'Kaled? While assassination and subtlety rogues can blindly equip the legendary quest daggers at each stage, combat rogues have to make a decision. As I've said for years, rogues spec for their weapons. You need to round up all of your available weapons, and then mix and match to find the right combination.
There are three different levels of No'Kaled, and there are also three stages of daggers we receive from Wrathion. Between all of these weapons, there are nine different possible combinations that you could have today. Your personal arsenal of weapons is dependent on your Elementium Gem Cluster acquisition rate and your luck with Madness of Deathwing drops, but chances are that you have at least one version of both the quest daggers and No'Kaled.
