I suck at maths, but isn’t it worth playing in Berlin and Normandy right now? With the new update we will have to pay for each item, and consequently those who want to play in any rank must shell out 5/10/20k silver or more for weapons, planes, dogs or ostriches which could unlock now in a flash.
Now in the campaigns of Berlin and Normandy there are both early war weapons and late war weapons, all more or less affordable with the grinding: playing f2p you can get most of the weapons in a shorter time than in other campaigns.
To give some examples:
-PPS-42/43: in Berlin respectively starter pack and lv8 (in Stalingrad lv16 only 42);
-M1 Garand: lv7 in Normandy (lv13 in the Pacific, lv25(yes, 25) in Tunisia);
-MP 40: lv9 in Normandy and lv8 in Berlin (vs lv14 in Tunisia, lv11 in Moscow);
-SVT 40: lv7 in Berlin (lv15 in Stalingrad, but you have to pay to get it);
there would be many other examples and obviously it doesn’t apply to any weapon (see the M1A1 in Tunisia compared to the unlockable one in Normandy), but this can be useful to be able to save time and credits in view of the new update!
I’ve probably reinvented the wheel with this topic, but hope I’ve been of some help for some of you.
