Actually, it is based on your level until you go past level 30. After level 30, you will use a minimum of 30 AS even if your attack team uses less than 30 AS. However, I don't know exactly when the minimum AS usage starts following your level because I have a level 10 account that is still able to use only 5 AS to attack.
