For me, Bryan Hitch is from the Alan Davis school of cartooning, he's always been good at this kind of thing, especially on The Authority.
Its hard to try and define the line where the writer and the artist come and go. With Kirby and Miller being one and the same, its obvious its one creative mind, but with multiple people? I don't know if it was Waid's idea for Samnee to use irregular panels to emphasize certain actions and positions
but surely he's got to get some credit for coming up with the scenario, pacing out the beats, playing with reader expectations, drawing in tension-the reveal-the surprise beatdown with the murdock flashbacks
Probably more on the artist than the writer to hammer the visuals home, admittingl. You could probably write a really bitching action sequence, but if the artist can't make it convincing or uses some poor choices...
