So, I have a few comments. I'm looking at this academically and based on past game experiences, and please don't take it as an attack on whomever set the event up but sometimes you gotta call things out in a polite way to see changes in the future.
That... uh... doesn't look like a very balanced setup, IMO. The Boston and the Tu-2 (a 1944 plane, by the way) have a top speed that matches a 109F to mid alts. Meanwhile the Tu-2 is nearly 2x as fast as the He-111, and about 100 mph faster than the Ju88. And it has 20mm cannons and can dogfight when needed.
The min-max fighters on the axis side are significantly outperformed by the min-max fighters on the allied side. The no-max fighters are the only area that is close, with a slight edge to axis at high alts only.
And, finally, as a Bf109 fan I have to note: The Bf109E-4 is noted to be placed in to replace the Bf109E-4/b and E-7/b, which were common during this time. However, the main point of these planes during this campaign was second-tier units running jabo attacks. They were not tip of the spear and were not your front line fighters. Why is this a problem? Our Bf109E-4 doesn't have a bomb rack, last I recall. They made it a pure fighter only.
Again, not trying to pick a fight. Trying to start a conversation about some things that need to be considered.
