At least i have a base to backup what i am saying, plus Ddraig is slightly stronger than Issei after drinking that indu milk amitra, you make it sound like Rias can spam time stop like there is no tomorrow like any other ability it requires stamina and Rias has a very low one compare to others.

And again... do you know how to do math? Fenrir 80% is no where near heavenly D class and still time stop could only stop him 1 sec or less if he was in his prime rias would have lost instantly gasper needs to see the target in order to activate his ability Fenrir has speed feats he can move at god like speed in his prime. and Draig>Prime Fenrir/Typhon.

I am done with you, go on keep making your own headcanon.
