So I find having it on the B button is just not effective, I cannot risk to move my finger off the RS. I will not use other control schemes, as fish sticks works best for me, however the ability to reassign ground pound to (RS) melee (or any other button/stick of choice) would allow a double click in air to activate it. Looking back I can think of a few situations where it may of been beneficial to use, however using the Lightrifle (P.S. Whoever had the idea for the scope, pay them more, my mind was blown when I first used it.) was still (even in this accidental CQB) a better choice.
I believe this could make ground pound a far more attractive option than it currently is.
