@FrankieX98 I think I do^^

seems as if Katarea, Shalba and Creuseroy are either not blessed with their Bloodline Ability (nobody now how far they are descendant to the Original Maou) or they are not fully trained in it (the Civil War is 500 Years ago...they by himself cannot be much older or they would have fought in it) or they are simply weak (even with Ophis snake Katarea could beat Azazel...I think since he blocked her empowered strike with ease he would have won even without his Arteficial Sacred Gear)

I think it is a mix, they are arrogant and dont train their asses of as Sairaorg,Issey and Vali...they are not complete trained in their Bloodline Ability (they were young as the other descendants were killed) and because of that weak.
