,No More Micro Transactions
The first change is the removal of micro transactions from progression. We wanted to remove the need to make purchases to progress your player and just focus on the gameplay and more pure experience. So this year, you will no longer be able to purchase Training Points. Instead, you will experience a new way to progress your created player, but I will get into that later. The removal of micro transactions from Road to The Show also means that you will no longer be able to heal injuries through stubs. You will just heal naturally.
