Fair point. Would've been better if she she got stronger on her, used the sword the church gave instead of waiting for her future child to be born(that way she could show that she learned swordsmanship under her brother's knight due to her interest in japan, and started training again to not only get stronger but so she would be able to fight even if her magic powers were temporarily sealed like in vol 11.), and if she gained her transformation similar to her brother's super devil form(like this; https://dxdfanon.fandom.com/wiki/Rias_Gremory_(Midnightverse)#Forms), without issei's, gasper's, or any of her servants help, which would truly prove how strong she is with or without issei, and she can stand beside him like wishes to(she said so in vol24).
