Allies demand a lot of coordination and being super aggressive which is hard for new players to learn.
This only applies to Amis and Soviets. British are incredibly easy to pull off. I´ve seen my brother play them on noob level. Put a Vickers into a building at an important point and then tech up to Brens and Cromwells. There isn´t a lot of work involved. You will dominate the mid-lategame anyways with Cromwells, Comets/ alternatively super engineers and Crocs.
Also lol at Panther nerf. I suggest OP to try the vehicle instead of complaining about it. See how your precious Panther does jack shit and gets picked off by every AT weapon on the field bar the T-34/76, Cromwell and stubby Sherman.
