If you're genuinely trying to improve yourself and become a better player, the first thing to do is stop blindly following tools such as Mr Robot. As people have pointed out, a big consideration in resto druid reforging is haste tiers for additional HoT ticks. By all means read EJ and sim your character in Rawr/MrRobot/whatever, but do so only as an aid to your understanding, and always understand WHY you're gemming/reforging a certain way.
