I would think Crom's lack of teamwork would hurt him, not the other way around. It would make him, say, more vulernable to a trap than if he worked with Rias's team on a regular basis. Plus, he is composing a large portion of Rias's team's strength, him and I'd argue Vasco, Gasper, and maybe Kiba are what're going to make that match very hard for Vali's team and Issei's team eventually. We already know Gasper is OP since he outclasses both Dimension Lost and Sephiroth Graal, Vasco is at a younger state which means that probably only Arthur can handle him, and you have Kiba, who can steal the holy attributes of Caliburn to decrease Arthur's power.

I'd probably suspect Vali's play maybe a straight forward fight with Crom initially, and then probably target Rias if things go sideways. If it was Issei, its more likely that he might try and trap Crom temporarily, so he can widdle down Rias's numbers and then focus solely on Crom to give his team a fighting chance. The fact that Rias is the King and not Crom maybe a big flaw in the team's structure.
