The point you are constantly missing is the situation. Again, if this was a life or death situation then you would have a point but this is a rating game. It's a friendly competition. This isn't a death match. You are clearly underestimating Issei's resolve. Remember that in volume 22, he declared he would defeat Rias. Sure, he's fighting his friends but again, it's not a death match. If they get defeated then they simply retire.

Rias is a princess but why should that matter? She's no stranger to combat. Also Rias would feel insulted if Issei went easy on her. Rias and Issei are both competitive and hate to lose. If anything he would just use one of his perverted techniques such as Dreak Break.

Also you clearly did miunderstand what Sakra was saying about Ravel. Sakra brought up the fact that Issei relies too much on Ravel. He just needs to think more. The issue with Ravel was her trait of "Supremency" which clased with Issei's trait of "Rightenous". Ravel's mother brought this up in volume 24. But that issue was already solved.

Issei has come a long way and has learned to keep his emotions in check during rating games. Volume 22 is proof of this when Baraqiel outsmarted him and trap Rossweisse and in volume 25, Issei didn't overreact when half of his team was defeated. Again, he's come a long way just like Roas has which is why she had no problem showing Strada her resolve to fight Issei. After all the things Issei has been through such as defeating Rizevim (a Super Devil) and Apophis (Heavenly Dragon class evil dragon), you think Rias was worried about Strada? When Issei has defeated stronger enemies?
