It would be great to get an impression from Amsoil who spend most of last tour in the spit14. Seems he has been in the K4 most of this tour. When i asked him about the 14, he said in essence that it was not as good as the 16 (I laughed and said that there were several times when i killed him where had he been in a 16 he would have killed me, and when he did get me, the 16 would have had me 1 o two merges earlier at least - which I think he agreed with).
Sure it is a great plane above 24k, so is the TA152. . . in all honesty AH2 is really a sub 10k game (which is why the LA is so dominant. . .really really imba powerful plane in AH2) with some fights starting at 15k. But the only time I have ever gone above 15k in MA was to go buff hunting, and if I found a plane, we would spar, but I would not follow him/her down to the deck.
Which is really why if it were unperked, I really don't see it affecting the MA that much at all. It accelerates and climbs great, but that is really it.
