Why is it important to maintain a balance between state and national authority in a federal system?

It is important to maintain a good balance, because if the states are given to much power they would no longer need the federal government and likely leave the federal government. If the federal government is given to much power the government would likely resemble a dictatorship since states wouldn't have a say in the laws that govern them.
