The lineup is fine, you cant fight head on with german tanks though, you need to flank a bit and use your stab to play peekaboom. The 76mm should have no troubles 1 shotting almost everything it fights honestly.
The Jumbos are in a weird spot, I still can do well with the 75mm jumbo but at 5.7 it is a bit overtiered, and you have to be creative in your gameplay with it. I also wouldnt bother taking it out as anything other than a last spawn if you are bottom tier.
not too bad, i’ve gotten multiple 8+ kill games in the past 2 days with it, and i’m shit at the game
my lineup is the
M36 GMC
M4A3E2
and the two 5.3 and 5.0 76 Shermans
(and a little F-82E for CAS)
