So today I wanted to discuss what factor I use to determine what the stats are for making a card. I base all my stats off of the sherman do to its stats being the closest to the Pounder. Its 75mm cannon's stats are only 1 less than the Pounder's 17pdr. With that being said I configure a basic stat chart for tanks on how to calculate them all. As for weapons just play test them and don't go extreme on the unit. Just because they are your unit doesn't mean it has to be a god on the board. My tanks I try to make a standard. Unless they are suppose to be warmachines or gods like the German Landkreuzers or Superman.
The calc chart is Here.
