It's easier to think of hit as "reduces your chance to miss" than "increases chance to hit".
Getting more hit means your crit cap will be higher. That's why fully buffed, Boots of the Shadow Flame are going to be slightly better than Chromatic Boots.
Through trial and error I figured out that Attack Power is king, aside from obscene itemlevel/itemization differences.
Over the years I've seen all kinds of numbers, and I started caring less and less about the decimals behind the comma. Just as an example with random numbers: I couldn't care less about whether my effective miss chance is x% or x.24%.
With that in mind, I have made my own guide for dw fury, with inspiration from an old friend from ED named Hiddeh. If anyone is interested, leave me a pm.
