We are in need of a official response to the healer situation

[Feidam]

Because I could just use Glare in that time and heal the tank with Tetragrammaton or Benediction instead. I need 3 GCD heals plus Misery (also GCD) to get one Misery off; that's 1200 potency in the first case, and 900 in the latter. And I think we all learned in elementary school that 1200 > 900.

You are ignoring movement periods and are acting like people are suggesting just fishing for misery. Although I am sure some folks will just fish for misery.
