It depends on the enemy i believe, Helli against non organised army like Taliban and ISIS would work but against Porkies hellies would be in trouble. Helli's would have issues carrying heavier bombs and missiles only hellfire.
I would rather have us a modern fighter craft which can play CAS role! I know we are getting those 22 american birds but we need a proper plane like Su-24. We don't need bombers for sure.
