What kept me playing some time before, was free content. I know you guys are running a business and can´t give everything new away for free. But I would think player numbers would go up again if you just released some new free commanders like the community defense commanders, German infantry commander etc. It doesn´t have to be big.
Also after some time with always the same units every game will come to the point where there´s nothing new. Adding even one new unit for everybody in a free doctrine (like the new, big Russian MG) could change that. Maybe a Su-100 or a Jagdpanzer IV doctrine.
