(The following is typed under the assumption that this is not a hoax and the Spitfire XIV is going to be added like the P-47D-30 and P-47D-25 were, in version patches not in a new version)
I hope that the 14 is not too expensive. If it costs 60-70 points I will only be able to lose 2 per month, when the time/performance comparable aircraft like the Bf109G-10, Fw190D-9, La-7 and P-51D can all be flown and lost for free, as many times as you want. Contrary to what many on this board think, the vast majority of AH players, either through low play time per month or lack of skill, cannot simply fly as many Tempest priced aircraft as they want and infact take multiple sorties to earn the points for an F4U-1C. I think the goal should be to control the Spitfire XIV, but not eliminate it. I never see Tempests, F4U-4s, Ta152s, Ar234s or even Me262s nowadays. When we look at how often those aircraft get used, it is something like 500 times per month on average. The Spitfire MkXIV entered service on Jan. 2, 1944. Earlier than any of the other 4 fighters I mentioned in this thread, more than 9 months before the Fw190D-9.
The Spitfire XIV will already be operating under the handicap of being gangbanged wherever it appears, the icon ensures that, while lacking the required speed to escape, many fighters being faster than it as AH combat altitudes.
If it does cost 60-70 perk points, well, there's always the CT.
