The SPAA at 8.0 to 9.3 is considerably better than 8.0-9.3 CAS, because that CAS very rarely has anything better than CCRP bombs or a couple bullpups. Is facing a gepard in an F-84F really a fair fight? How about facing an M247 in an Alpha Jet or G.91?
In fact the CAS/SPAA imbalance at that BR is so bad that CAS is quite rare in my experience, and it’s to the point where it is common to not see more than a couple planes in an entire match.
It also should not be 8.0, but rather the same BR as the 15bis.
Don’t forget how the Italian CL-13A Mk.4 is roughly same performance as the F-86A (a bit heavier, depending on your playstyle this could actually be a detriment for you) so for the sake of dramatics I’ll call it actually worse than the F-86A-5.
It’s somehow at 8.3. The exact same plane but Italian is 8.3.
