I’d do either USA vs Germany OR USSR vs Germany
Ruleset:
- Scoring as before
- BR2-ish
- Confrontation only
- Upgraded weapons
- All semi auto/full auto weapons get large ammo bags
- Squads should have at least 1 engineer available whenever possible
Squad lineup:
- Engineering
- Assault
- AT
- MG
- Guerillas
- BR2 Event paras
- APC
- Medics
- Medium tank
- Sensible fighter/bomber
Reasoning/caveats:
Confrontation only since it’s the only mode that makes sense for the event, with how they way scoring works. I remember being mad about wasting entire evening without improving my score because I’d get like 5 hours of defences where enemies refused to leave spawn. Confrontation means the matches will either be quick or intense and therefore most will have a chance to improve the score
The high squad amount is to mostly let people with different play styles have options (It could also show people why more slots is more better)
Bombing raids should be disabled or their score removed as it’s trivially exploitable to rack up insane scores for doing nothing, especially if one gets a collaborator on enemy team to just constantly send them in
Tank combinations I can’t give input on, as I do not use them at all. Last Even Fight I remember had a joke of a pairing where one tank could not contend with the opposing one at all. In my rough experience it should be something like Pz3J1/T50 or Crusader/Pz3J1 (disregard if its lopsided and suggest better pairings)
Plane pairings: Previous Even Fights had insane pairings where one side had a plane with no forward facing armament…
I’d suggest something like Soviet P40 vs IAR (since CAS options are super lopsided. The Su-2 or IL-2 completely dumpster any Stukas) Argument could be made for IL-2 vs 110 C7/F2. If USA vs Germany I’d do P38 (with M8 rockets) vs IAR again (Germany is really missing a BR2/BR3 fighter with 20mm 151s AND bombs 
) The planes BRs are a bit mismatched because of how loopy they are…and how undeveloped some factions are in this department
Suggestions are welcome. I mostly suggested these pairings because they are the most rounded and in my experience quite viable against suggested opponent, without completely dominating/getting stomped
Just make sure weapons for troopers aren’t completely unhinged. You could give the BR2 semiautos to the engineering squad, some funky smgs to the medics and guerillas, slightly off-meta, but reasonable smgs for the assaulters. Some squads could be purely bolt action loadout. Have each squad be somewhat reasonably themed instead of loaded with “random loot generator” where each trooper is carrying some random crap.
If you give a BAR to the US don’t give the Germans a damn Breda MG. Make sure the weapons are upgraded
Why do this:
It’s fun. Also, people could see why extra slots/premium can be useful. You could run a sale on slots.
But, overall, IMO it’s just a way to do something different, have people engage and maybe see the game at it’s best. Also, because it would only have one queue you could test some things out. Give it loose balancing (as in, both teams have players of ROUGHLY same skill vs EVERYONE is at the same skill level), have the matches only start when there’s enough players for both teams. No stacks OR stacks play vs stacks only
You could incentivise people to join by letting players earn one crate per 5 matches for example
