If a tank is blinking a lot and in danger of dying, it's probably because he's trying to stay alive, and in turn keep the party alive. You should do your best support him in this, which means using macros that aren't affected by the blinking problem. If you don't do this, I think you are a terrible healer. Maybe you should pick up a different job?

Each second I save on my utsu recast timers from swapping from eva into haste gear is a cure you don't have to cast, you should be thankful.
