I totally agree with Paavopesusieni.
Also wide open maps for long range fights are nice. Shouldn´t be hard to include some "Russian Steppe" maps. The limit however is our good old fog of war. I doubt field of vision could be improved without slowing everything, especially on the 128p server. One should however look that infantry doesn´t become totally useless or it ends up like a lot of the North Afrika maps, where someone lucky gets the tanks and the infantry can´t really move.
