Ok then lets make stuka dive bombing a clone of "Allied air supremacy" and "light artillery barrage" a clone of "artillery cover".
As I have explained in previous posts, cloning things does not make things balanced unless you clone the entire faction and commander.
As I have explained in previous posts, most of issue of "stuka close air support" come from the commander design that include g43/tiger/stuka.
As I have explained in previous posts, all loitering planes need an overhaul since planes are hard to counter in 1v1 and very in 4vs4.
There is no issue with Stuka close air support the ability is balance from my point of view. But it is interesting that you don't want the P47 being equally powerful and do the job it was design for.
