The only good maps on the 1v1 map pool is Kholodny Ferma/s and Minsk Pocket.
lol
Minsk is one of the worst maps in the game and its due to the design of having a map made of of linear lanes. It reduces flanking and increases camping 10X and it ends up usually being who gets their 100 range tank first and doesnt lose it.
Other bad maps are Langres Winter for its terrible deep snow placement that punishes flanking and tactics and increases camping.
And of course Stalingrad is just a disaster.
