Well, as some people have already mentioned, there are Gods in this tournament, so its not like its that unfair. Vasco is strong, but there are plenty of people stronger than him in this tournament. Crom on the other hand is probably in the Top 10 if he's stronger than Ddraig and Albion, so that's pretty OP. I would in relative to the other Young Devils, like Vali and Issei's team, its sort of unfair, but when you got guys like Indra and Typhoon playing, its not.

However, I can't really see the rest of Rias's team being that bad to fight against. I mean, its impressive that she's added two Longinus, Graal and Incinerate Anthem, but as far as we know its still dangerous for Valerie to use Graal, and Lint "just" got Incinerate Anthem, so its not like she's going to be a master, its going to be no different than when Issei first got Boosted Gear.

So, honestly, I feel her team may rely heavily on Vasco and Crom in the later fights.

Also, Issei's team is getting pretty OP as well. He may interchange Elmenhilde and Roygun as Rooks or Nakiri and Ravel as Bishops/Pawns. Either way, Issei's team is getting pretty strong too. His Queen is stronger than Rias or her Queen, Rossweisse is possibly stronger than Koneko. Xenovia may very well be stronger than Kiba. We also are not 100% sure what Bova and Nakiri can really do, but Rias is limiting herself with Crom even though he is OP.

So, basically, if Issei's team fights Rias's team, if Issei can beat Crom Cruach, the rest of his team could probably defeat the rest of Rias's. Roygun, Bova, and Nakiri could all gang up on Vasco, and Issei could join in if he beats Crom.

Basically, the team isn't too OP if you look at it objectively, if they face someone has strong as Issei, they need Vasco and Crom to carry them.
