I'm sure you could make it 2:1 by timing it manually and allowing the auto to fire, but that defeats the purpose of having a macro in the first place as you are bringing human reaction time back into the mix. For now we've both went back to 1.5:1 as it is just as serviceable as 2:1, we just have to keep a closer eye on the mana bar now.
