i must say that this is the worst map out there, the main bases are too close to the ridges and it's almost hopeless with the axis as you are totally no match of the Shermans and 6 pounders out there....and arty.
a suggestion would be to move Axis main further south and give them one more tank, or make the map concentrating on one ridge (Kidney) to make gameplay more intense. perhaps 1-2 pushable 37mm PaK for fire support as well.
another suggestion would be to change the map to "counterattack" type of map, like sidi rezegh, where the attacking side would spawn a bit more stuffs so the balance would be kept better, still, 2 ridges is a bit more for 32 players (though 1 ridge is a bit less for 32 players...)
