How do you explain...?

If anything, I've fallen into the trap of thinking lower numbers = faster attacks; mainly because I've been indoctrinated by how WoW displays weapon speed (Where a 2.90 speed gun is faster than a 3.00 speed crossbow).

Nice consistency there, Blizz.

What is more important is to be consistent within the game. I think that if you are going to have modifier like "Increases attack speed x%" then listing the weapon speed in seconds per attack is a bad idea. Because then people have items with +% modifier which actually lower the base stat as they see it on the screen. And the percentages are not equivalent.
