Have been doing land combat with GS on, 200 or so fighters within range, and only a few are flying escort duty so am getting masses of bombers shot down by Soviet fighters. I didn't take screen shots.
So set up a test bed.
This is T2 of RtL.
The first two combats have GS ON for Axis and GS OFF for the Soviets. This replicates what is happening in my server game. Not many 109s are flying with the result that many bombers are shot down. Actually in my live game it is going much worse as the Soviets have better fighter cover.
The first second combats are with GS ON for both sides. As you can see lots of 109s are flying and lots of Soviets get shot down. Axis have sufficient fighter cover to protect their own bombers. All well and good for Axis.
Adjusting the GS percentages doesn't help.
Supplies for the fighters is not the issue.
Are other players seeing this ?
Has there been a change with the latest patch ?
