Probably the best mod to add if you are doing physical damage with your weapon. Even useful for Sorcs if they are using Lightning or Chain Lightning, since those rely on swing speed for their casting speed. The fact that this one can't be found on Rare Jewels is probably the biggest strike against them for combat characters. Fervor vs. ShaeShael: The Shae Shael Rune (#13), adds 20% in a weapon and is harder to find. 15% or 20% will give you the same frame rate almost all the time, "of Fervor" jewels work in things other than weapons, and you can get a nice prefix on the same jewel, so in most cases an "of Fervor" will give you a better result.
