I agree with @Omega64, Rias catered too much on personal battles instead of trying to win. Issei team put aside personal battles to focus on winning. This was made clear with church trio. Xenovia and Irina didn't want to let Asia fight Crom alone because they knew she couldn't win but Asia insisted and told Xenovia and Irina to go ahead. To which Xenovia complied because they knew the objective to win the game.
