I also agree the strike zone should be bigger and the mound moved back to 53 feet.
But I will never understand the thought process behind moving the bases back. 70 feet on 300's is perfect. A double is a double. 75 to 80 feet on the baseball fields is also perfect.
If you move the bases back beyond this you are excluding slow runners from playing. They would be getting thrown out at 1st base on a single to the outfield.
