This is not gonna be a fun post for me because, well, I goofed. I made some seemingly innocuous changes to the spreadsheet a while ago that caused it to be less accurate than it normally is (which, for the record, has never been anywhere near 100%), and it’s taken me a while to figure out that there was a problem and then finally fix it.
The short answer is that the spreadsheet has been overvaluing crit since 7.1 was released. In this updated version, you’ll see stat weights that look way off. Specifically, crit is much lower and haste is much higher; this is due to several reasons. The first is the previously mentioned changes that caused crit to be inflated. Second, I had been manually reducing the weight of haste by 10% because of its adverse relationship with mana; I’m no longer doing that. Last, stat weights are going back to what appear to be much more reasonable values, but everyone has been under the impression that crit was so powerful, so they have gravitated toward gear with lots and lots of crit. This makes crit look weaker than you would expect simply by virtue of having so much of it and so little of everything else. By comparison, the other stats will be higher than expected until stat distribution evens out a little more.
