The problem is that a 1940-1942 server would probably be empty. The late war aircraft are powerful enough that the average pilot can get themselves out of trouble a little bit quicker and the armament is powerful enough that they might get lucky and spray the target with enough lethal lead to make it count.
Thats not to say that you can't do the same with a 109E-4 against a Yak and dewing it just as quickly...but it feels allot better with the big explosions from a 30mm or four 20mms.
I do like the early war battles allot but I get bored with just one scenario...I like a mix and thats what a few servers are willing to give me. But I think if a server were to specialize in early war only...it'd be empty most of the time.
I'd suggest flying somewhere where they do have the kinds of scenarios you like and quite honestly learn to like the other scenarios for their own reasons. There are scenarios that I didn't like...including all of the eastern front when I started with IL-2 (but the demo was good so I learned) but now I have allot of fun there. I might have more fun in the mid war low level battles on the east than anywhere else actually. Thats my suggestion...take it or leave it as you wish
