Here are Tour 1 K/D ratios (as of Jan 25th, 8.30 GMT+1). The sample is still very small, except for cannon Hog, whose number of kills is already greater than it used to be for whole beta tour for Macchi.
Plane K/DF4u-1C 2.28 !!
Fw 190A-8 1.20
George 0.92
Spit IX 0.91
109G-6 0.86
P 51D 0.82
La 5FN 0.72
C 205 0.70
109F-4 0.65*
F4U-1D 0.63
109G-10 0.61
109G-2 0.38*
* means that the plane has very few kills and deaths, so K/D might be off quite a bit after few days.
Your thoughts, plase

Here are mine.
Cannon Hog kills everything in the arena. Either everyone who understands of lethality has moved to it, or it really disbalances the arena (700+ kills, compared to miserable 50+ kills of 109G-10, for example).
Poor turning ability, poor six view did not hurt the Hog much, it seems. Everyone is on the recieving end.
It's a new plane, so this should not be disregarded. Everyone wants to try it, I guess.
Its record might also have something to do with prevailing HO mentality in AH.
190 is same as before, and I'd say the quality of pilots has most to do with its record. They all flew WB A-8, and now they feel like they have wings

Big-guns-good-turn planes hold 0.9* K/D ratio. It might be far better if those weren't the one way ticket planes, used to defend vulched fields.
Moderate turners, moderate guns hold 0.8*-0.7* K/D. Fair enough. My guess is that few have taken time to explore these planes fully and fly them correctly.
Now, my real question is who is guilty for such a lousy record of the G-10 ? It is a superb machine, and you waste it so easy. Bah

G-2 has indeed poor record, but it wasn't flown that much, so things can change. Still, it is a good all round plane, comparable to Macchi, guns somewhat weaker.
