How about let us select the nations we want to play?
If I just want to play US and Japanese to increase chance of Pacific let me. Or alternatively Axis and US only.
Also Any should give XP bonus imho
PS Bugs are getting annoying again, stretchy, invisi planes, weird in game customization despite specific appearances, broken tailgunners… please fix soon 
I say they should fix the queues and a some BR weapons. Rather have the queues be 1-2,2-3,3-4 and 4-5 with just early maps being in 1-2 and 2-3. 3-4 would have a mix of early and late with preferred maps depending on what’s in your rotation. And then 4-5 just have Berlin and Normandy until more campaigns are added in for 3-4 and 4-5.
Example: eastern front
1-2:Moscow and Stalingrad
2-3:Moscow and Stalingrad
3-4: just Stalingrad and Berlin and when more eastern front campaigns get added like Leningrad, Kursk, narva and dneiper carpathian
the map choices for the preferred maps system will open up more.
4-5: Berlin until they add more battles as well.
Eastern front weapon BR’s changes
PpSh- down to tier 4
Ppd40- foldered with ppd 34/38
Federov- rpm nerfed to between 450/520 and knocked down to tier 4
Avs- down to tier 4
Kiraly- down to tier 4
Mp717- also on tier 4
Mkb 42- down to tier 4
This should make it to where in the earlier wars if you want bolt actions and low tier smg/lmk, go to the lower two queues. If you want to do early stop but play with higher tier early weapons, go to 3-4. If not a four queue system, then they can also simplify it to 3 queues being 1-2,3-4 and 5 by itself.
