I´m not a new player. I play the game since preorder. I´m not very good but I´m an avarage player (and sometimes a good player). But I have some limits (i can´t play with keyboard; i only play with the mouse)= I have 52 yo. It´s not easy to me to learn to play otherwise.
But I feel a lot of times that soviet infantary (enginners and conscripts) and some tanks (t34/85 and IS2) are underpowered. I feel that bunkers could help more to defend conquered territory that otherwise is hard to defend..
I think you should start a thread in gameplay section asking top players for some help. It is much harder to convince community and developer to change a game than to simply try to get some new tricks and strategies that will work better.
I can give you some advice for defending with soviets here though. The conscript is a micro intensive unit, so I would recommend not using it too often if you don't use hotkeys. Instead try maxim mgs for defence against infantry. As for infantry it is a good idea to go guards, as they are great in holding ground against both infantry and vehicles. These two units supported by well placed zis guns are only possible to displace with artillery. But it is a different subject.
