I think Issei has been made to look weak plenty of times already, whenever he gets a powerup, the author gives vali the same powerup but only his is more powerful.

At the start of the RG arc Issei already got many bad reviews prior to his match against Barakiel, thus he already has all the bad experiences.

Being near the end of the series I would like to see a glimpse of Issei's power from the EX side story being shown here which would solidify his growth from not having enough power to use teleport circles to surpassing heavenly dragon class by convincingly beating a strong opponent.

Dulio has nothing to lose by losing to Issei and his character really did not gain anything by winning, having Issei doing the job to dulio really makes little sense to me

Hoping the RG against Typhhone will a direct battle and not have some wonky rules like scramble flag added to it
