Just did a little study on the Spitfire data I have vs the AH performance.
It looks like AH's Spitfires are slower than the ones I read about (Spit I, Spit IX, Spit XIV), and with poorer climbrate (at least spit XIV). So, a bit Porked. Spit I's get outrun by 110's, and Spit XIV climbs less on 25% fuel than fully loaded in tests in ww2.
Spit XIV also turns significally worse than the IX, unlike what reports state.
I think there is a gameplay reason why we don't get the uber Spits. They are simply too good. AH would be flooded with Spits and Spits again. Any newbie would be a serious threat in his uberboos Hizooka Spit. That monster plane would outgun, outturn, outroll and outclimb the dreaded N1k2 for instance.
It is not fair, but still, for this is a game right? Aces High or Spitfires High?
However the Perk system could be used here with some sense, the Perks are just generally a bit to high now.
Bring them in!
