Naa.
It would still be full of P-51s and corsairs. If I am not mistaken, (Lusche the statistician would know), the P51 is the most flown plane in the late war arenas.
And as others said, never underestimate the Hurri IIc. Always give them respect and if one has altitude on you.... live in fear. If one is less than 1k from you even at a full deflection angle.....live in fear. Even as mediochre a gunner as myself frequently score kills with hispanos at D800 on 90 degree deflection "pings". 10 ENY is a good value for them imho.
