If you get the buff that increases your haste then wouldn't it be logical to assume that the up-time any of the RPPM trinkets would be extremely high during the encounter? I had 3 stacks of the haste buff during our kill last week and yet my up-time on bad juju was extremely low, only around 7%. Clearly that fight I had some terrible RNG, but is the haste from the buff not considered "real haste?" I know there is a lot of controversy going around that haste is still not worth gemming/reforging for over mastery, and I believe I remember reading that Ahdehl from Blood Legion said he had tested a full haste, full mastery, and a good mix of both build, yet he said he was still having better results with the full mastery build. Regardless of what shadowcraft shows, I feel like haste may be better on paper, but mastery better in practice because it's more consistent. What are some of your guys thoughts?
