As of today when I last checked, the A-8, A-5, and F-8 all share an ENY of 25.
190a8 and 190a8 were swapped I think. The A8 is by far the more lethal of the 2 but had significantly higher ENY level (meaning it earns more perks per enemy kill) than the A-5. One would think the more capable plane has LOWER ENY.
Here's the kicker, the 190F8, almost a clone of the A8s performance, had the same ENY as the A-5. Thus, I suspected for quite a while that the A-8 and A-5 had been swapped for each other.
Unless HTC has some other justification for doing it that way? Maybe they thought the more manuverable A-5 was easier to kill with? I don't know if it was oversight or intent.
