It is IAS because it is an attack, just like a Dtalon, Dclaw, and Dtail.
You got it wrong. Dflight is based on FCR. My trapper Dflight alot faster then any of my other sins did. And the y difference between my trapper and the rest when it comes to IAS was 1 frame. 7 fpa claw vs 8 fpa trap casting speed with wiz spike. And you hardly see any difference between 1 fpa.
The other difference was that my trapper has +102% FCR , while my other sins don't have any FCR. There's a difference of 4 or 5frames (14/15 without FCR , 10 with 102% FCR) And you do notice that alot.
So Dflight = FCR based , not IAS based.
