For dual wielding
With RE the more haste we had the more reliable was our resources generation which made haste really attractive and at times (depending on gear) better that mastery.
With the blood tap priority and resources generation being more predictable and reliable, couldn't there be a kind of haste cap ? Not really a cap but a level of haste where your enough comfortable with resources generation to focus on crit instead.
Maybe am I doing something wrong but when I sim (simcraft build 505-4) stat weight with the bis profile available here (Simulationcraft Results 505-5 (r14518)), haste seems rather low compared to mastery and crit.
