I was reading over at another forum about haste, and I am unsure if these values still hold true because the same thread also said that you only needed 446 hit rating to get to the 17% cap.
Are these values still correct:
Haste, DoTs and You in 4.0.1 and beyond
Below are the values of haste needed to add another tick to the damage over time spells we all know and love. These are only for the base spell and does not account for any change by talents and/or glyphs.
Almost everything in this thread is wrong. Especially the Mind Flay part as Mind Flay does not gain additional ticks now matter how much Haste you get. The sticky in the priest forums has all the Haste + hit information you need.
