Okay to get serious i have to say that this Stuka At strafe is strong, but the point is that i compair it inmmediat with the P47. After you do this it seems no longer to strong. The solution for me would be to nerf both but not just blame the stuka as OP.
Comparing it to P47 results in quite obvious over performance of Stuka AT loiter.
P47 is completely unable to wreck armor in single pass even if both planes hit, which is extremely rare occuranece.
P47 doesn't target infantry and team weapons, killing them just as effectively, stuka does.
The stuka have also excellent tracking, it'll get to half HP moving IS-2 in a single pass, show me the same being done by P47.
Stuka does what P47 does, except better, cheaper and it does more of it.
One thing that P47 have for them is the sight range, but that is it.
