Bustr is suggesting a counter to those who feel the 14 will imbalance the game in some way. The 14 will not, currently the 51D with its ords and high top speed is more then enough for the runners, add to that the LA and D9s and really what you have is a situation not where top speed is the absolute but that you are within an earshot of that top speed and have the alt to get the head start. If top speed and climb performance were the only factors, then all the 51 pilots would be in LAs - but they are not.
The 14, down low under 10k, usually under 5k, is not better then the spit 16, it turns worse and has a nasty stall. The people who can use a spit 14 to dominate can already do that in an LA or a 51 or a dora today - nothing much changes. Perked its rarely used, unperked it will have a few tours of popularity and those who like spits will probably go back to the 8 or 16 because they are much more docile and usable.
I feel that this is the same kind of argument people had when the 152 was unperked - and I think most people look at the 152 and and think "its not a dora, it's mine!"
So do we really need a G10 - no, not really. But will the spit 14 become the new 51? no, it can't turn, its got a nasty stall, and it could be argued that the 16 is a better sub-10k fighter, which is where most of the fights are anyway.
