Rias (Balor of Darkness) was only stated only to be above Maou class not God Class. Fenrir himself is at God Class if he's at 100%. If Rias (Baylor of Darkness) was at God class then she would rival Vali (Emperio Juggernaut Overdrive) to which you youself stated she was weaker. Issei (Cardinal Crimson) is above Maou class if you include old Maou. Barakiel and Kokabiel for example were Maou Class and yet we've seen Issei (Cardinal Crimson) is stronger than them given Barakiel loss to Issei (Cardinal Crimson) in Volume 22.
