Halo 4 control scheme is perfect, except ground pounding, which is quite cumbersome considering you need to bring your left hand to the right stick to aim it. There is a VERY simple fix: as I go to initiate a ground pound, the game should allow me to rotate my body with the left stick. If that is implemented, this control scheme would be awesome.
I use recon while holding my controller in the “claw” position, works amazing. I do understand your problem, though, and understand how that can be frustrating.
