Ooof the faction you seem to miss stuff the most from, if all are combined, is Soviets. But I wouldn’t recommend playing Berlin Soviets atm, it’s a bit tiresome.
Stalingrad Soviets might be a good compromise, especially if you got full access. If not, well in Moscow you still unlock ppd40, ppsh41, and even the Fedorov if you are into broken weaponry.
Stalingrad I don’t have full access sadly and I know grinding it again would be a pain but possibly worth it. Yes Allies Berlin scares me right now. Moscow I’m hearing a lot of good things about, I don’t even mind what guns are there, after coming out of allies tunisia I’m looking for a more balanced campaign I guess Soviet Moscow it is!
Well if you want the “good stuff” then Normandy Allies or Berlin Allies seems to be what you are missing, but both of those campaigns are pretty dead for the Allies so getting stompt basically every match will get old fast. I have 4 levels left for Berlin Allies, and only the final tank left for Normandy Allies but can’t bring myself to even grind for them.
I still have 10 or so levels left for Moscow Axis and then my grind will be finished aside from the levels I mentioned and duplicate gear (Normandy Panther G, Moscow T34 1941, and Pacific M1 Thompson).
Moscow Allies is heavily populated so now would be the time to grind it if you want to get Drum PPSH, Federov, T34, ect faster. Or buy Stalingrad Full Access and get KV, T34, PPSH, etc there (No idea what the player balance is there).
If you’re already halfway through with Normandy Allies, I suggest you to unlock the P-47 and at least the first Sherman with the 76mm gun. Heavy firepower that you don’t get in Tunisia, but it comes very handy to face late war Germans.
Also, if you can make it to the Browning 1916, that’s a beast of an MG. Worth it.
Healthiest playerbase you will find there is Normandy, both sides are always populated with real people. Berlin Soviet is just for suffering, at least that you are very good and have 4 human teammates to get into, Moscow Nazi the same as Berlin Allies, insufferable. Pacific i would recommend Japan because is the only country that is gonna be realted to one map in the merge. Tunisia is not my cup of tea, i have the lowest ranks there (both sides on 15).
Moscow Soviets are genuinely fun to play. The faction is very balanced unlock wise, by that I mean you’ll get your fill of early war bolt actions, early smgs, BUT ALSO the best smgs, such as ppsh41, ppd40 and Fedorov if you want it. You’ll also get the dt29, which I consider Soviets best lmg.
They’re also not too shabby vehicles wise, unlocking the iconic T34 (2 versions of it) near the end, and get the seriously exellent ground support plane IL2 near the beginning. Il2, is a bit like allies p47, it spits a lot of rockets and bombs.
Which means once the factions merge at last, if you maxed Moscow, you’ll be spread all around lvls, and won’t miss a lot of stuff, save for the best vehicles (IS2, Su85)
