Yeah. The Pocket Dimension. THAT is what's made stronger based on the strength of the competing teams in the match. The whole world knows that Issei and Baraqiel are arounds Satan-Class. So they made the PD strong enough to take whatever damage they dished out. The turrain inside the PD would still be the same as in the real world.

And Issei BLASTED A GIANT HOLE IN THE POCKET DIMENSION. Issei even went so far as to describe the hole. "A giant tear in the sky that had several swirling, irredecent colors."

Issei blasted a giant hole through a PD, that was made to withstand attacks from Satan-Class beings, as if it was paper. And you call that weak?
