Irina is no match for Lint. Lint has a Longinus that has reached Balance Breaker while Irina barely has Hautecleure which hasn't even shown to be particularly powerful. Strada is also not the same as he was in Volume 19, and he not only has a much stronger body, but also a stronger weapon.

You're also not counting with the presence of Yuuto. With Sword of Betrayer, Yuuto can weaken Holy Swords such as those of Irina and Xenovia and strengthen the demonic quality of his own swords, and with Glory Drag Trooper he can use all of the five Demonic Swords he has in tandem. He has also, according to the Japanese wiki, been learning from Strada to use Gram more effectively, restraining its aura at all moments except for the impact for less strain on himself and more powerful attacks. While I don't know how well he would fare against Xenovia, he can easily check Irina and probably can handle Rossweisse, while his ability to create Dragon Slayer swords along with his use of Gram can also allow him to check Ryuuta and Bova.

Grayfia teaming up along with Asia's BB could indeed be a problem, however that would limit her movement severely since she would have to stay within Twilight Saint Affection's protective field, and Asia is pretty much a sitting duck unless she has Fafnir who has restrictions, and the Evil Dragon brothers are barely higher than an average Mid-class Devil, so they are pretty much irrelevant.

Yes, of course I do see Rias struggling in that match-up. Struggling a lot. But I never said she was sure to win or that she would win easily. I simply said she has chances, and Issei's team also has chances. Most of the match-ups past the preliminares are not sure-win/loss scenarios, they all have chances to go either way. And even if the chance of one team winning is lower, it doesn't mean they are non-existent.
