Splitting made the game WAY too easy with the current values. I also liked the fact that no ore type went unused and you still had to mine on the top layers. To please both parties I think it would be best to lower the amount split to either 2 or 1 or add a % chance to get a certain amount back. For example 40% chance to get 1, 35% to get 2, 25% to get 3.
