There's another one who gets it. Because the Spit16 makes up for bad acm, it doesn't encourage learning it. There's lots of aircraft that are good for beginners but which still reveal enough mistakes to motivate growth. Here are the ones I can name off hand:
Spitfire VIII or IX
109F-4 or G-2
P-38L (no torque)
LA-5
KI-84 (great performance but gives lots of 'feedback' if you try to manhandle the controls.)
Leaving noobs with the Spitfire VIII is hardly going to deny them fun or kills. However, it is a little slower than the 16, its acceleration is a little behind and it doesn't roll like a 190 (almost forgot the 4x303s instead of 2x50cals). Maybe that's just enough to still encourage the learning of acm but with minimum penalty for new folks.
Give the 16 a small perk and unperk the 14. The Spit14 was never a problem in warbirds, and I used to love it when 14 pilots would try to turn fight me in the 109G-6.
With the exception of the Spits (in that list), all those other planes will do nothing but frustrate the crap out of new players and cause them to leave. I can't believe that the P-38L is even in that list.
The "Spit" whine is never ending and the reason being is that "most" new people do gravitate to the Spit as their "start out" plane. Now, if we apply the logic of "they don't learn anything" flying the Spit variants and must always rely on the "Spit" advantage, then NOBODY would be flying anything but Spits ... and we all know that that is not true.
The simple fact is that there are a whole lot of people who don't fly Spits, who first learned in Spits ... and I am one of them. I started with the Spit 9 (the "whine" Spit when I first started flying, since replaced by the Spit 16) and eventually moved to the Spit V and have since moved on to other planes, but what I "learned" in the Spits did translate very well to other aircraft that I fly or flew.
