The problem with the Mig-3, despite the support from vonKrimm or aper, is that it lacks the specific aura of 'representativity' which a certain, central line of fighters for a certain specific WW2 combatant nation holds.
What I mean by this - compare it with side by side with the RAF Spitfires or LW 109s.
Currently, it can be said that all the major/most representative variants of the Spitfires and 109s are introduced in AH2. The list of these fighters keenly matches the timeline at which point those specific fighters were considered the most representative, and even 'iconic' fighters of the given period.
The rivalry between the RAF and LW is represented with this current line up AH2 holds, starting from late 1940 to 1945.
Starting from the BoB in 1940
the Spit1 : 109E pair of 1940...
then it comes to Spit5 : 109F pair of '41...
Spit9 : 109G2 of '42
Spit8 : 109G6 of '43
Spit16 : G14 of '44
... and Spit14 : K4 of '45
Every advancement in aircraft from one side of the Channel, brought forth a match from the other side, and as a result the list the Spitfires and 109s, as the backbones of the RAF and LW repectively, become historically most representative line of fighters for both countries during each time period during the war - and this selection of fighters is what AH2 currently shows.
My contention, is that the Yaks and the LaGG/La line of fighters, are in the same league as the Spitfires in their rivalry against the LW fighters, in a warring front which started from 1941 and ended in 1945. It is only fitting that the Yakoblev Yak, and LaGG/La line of fighters get a full representation according to each of the time period which marks significant advancement in aircraft evolution, just as the Spitfires or 109s, 190s and etc.. got the same treatment.
Besides, the Yaks and La/LaGG fighters were the backbone of the VVS, the most important fighters in historical representativeness.
Thus, I think that the 'matchup' should be noted in the following manner;
1941: Bf109E : Yak-1/7
1942: Bf109F/G-2 : Yak-1B
1943: Bf109G-6/Fw190A-5 : Yak-9/LaGG-3/La-5
1944: Bf109G-14/Fw190A-8 : Yak-3/La-5FN
1945: Bf109K-4/Fw190D-9 : Yak-9U/La-7
It is only after the two backbones of the VVS, the Yaks and Las, get a full representation that matches the respectable lineup of the Spitfires, 109s, and 190s, that I think the other, less-representative-but-interesting options such as the Migs, should be considered.
