I am at a complete loss when comparing weapons for my protection warrior.

I'm still level 24, mind you, but between weapon DPS tooltip, weapon attack speed, and added stats (str, agi, etc.) which one is more important?

The main considerations I'm guessing are Rage and Threat output, but I have no idea how those correlate with the information of the weapon itself.

Example. This dagger is a lot faster. Is that better for rage? I would think so, but I keep hearing about these coefficients that make slower weapons proc more stuff better (nobody knows the actual numbers on them, ofc)
