I believe this chart is incorrect. For example, it states that with only a 5% spell haste buff, such as Ancestral Swiftness, as a draenei, I need 1,018 haste rating for a 9th tick on healing stream totem. I'm currently at 933 and I already have a 9th tick of healing stream totem. This chart also states that I need 3,049 haste rating for a 7th tick of healing rain, but I already get a 7th tick of healing rain.
I'm curious as to whether or not someone can provide me with accurate breakpoints.
Edit: Even at 843, I still have a 9th tick of healing stream totem, a 7th tick of healing rain, and a 7th tick of healing tide totem. The chart suggests that I would need 1018, 3049, 3049 respectively. Though, I am only getting 7 ticks of riptide. http://i.imgur.com/JtzFu.jpg
