Well Ddraig is not on Issei's team and it seems like Issei can only summon him in DxD which has an 88-mimute time limit.

I still don't understand how Rias is a glass cannon. You compared her defense to Issei which doesn't make sense as Issei wears armor. Essentially almost every character in this series is a glass cannon by that logic.

And how does Strada coming away uninjured fighting against Trihexa matter? So did the Rookie Four and their peerages. They all fought Trihexa off the coast of Japan.

And I don't remember Koneko one-shotting any mass-produced Grendels.
