Thanks for ignoring the words about the Rogue's very real high durability usage.
I didn't. But that, to me, is another problem in of itself that needs addressing. In my mind, stabbing and piercing someone with a dagger should not wear the weapon down faster than swinging a club or sword into someone's armored hide repeatedly.
In other words, daggers are taking durability damage too quickly, in my opinion. Honestly, I'm not sure if I like the idea of durability damage being linked to attack speed (AP cost) at all. Heck, I feel that skills like "armor specialist", "single-handed", "bow", etc should slow down durability loss - the idea being that as your skill with these items increases, you're learning to use them properly in a way that causes less damage from wear.
