I would love the idea... 88mm Flak and Brits fighting against Axis on desert maps...
But I dont think there will be a new faction... dont think there are that much people working on coh2 atm they are probably working on a new project otherwise the patches wouldnt be so delayed.
Dont lose your tanks... a vetted panther can easily fight against multiple allied tanks.
At least one OKW player should build a JP4... each Ostheer player needs at least 2 Pak40s and the tanks wont be a problem.
Dont spend all your ammunition on nades in the early game... lay down some mines instead.
