You don't have to worry about Rias's lack of power too much I have full confidence that she will become as powerful as her relatives, and I heard that Devils grow stronger in their powers as they older because anytime you have the Power of Destruction to have as a trait for your power you don't go wrong.

Rias will not be weakling sure her servants are powerful but don't count out her ability, and she has natural talents, and a very smart girl, and she works hard as well.
