On the flip side of that, Asia has been appointed the new President of the ORC, a leadership position. So she obviously has some leadership skills that have been underutilized, or Rias would have never recommended her. Xenovia is now the new student council president, another leadership role. And Ravel may be a daughter of a great house, but up until recently, she's been of a higher class than Ise, and is still a higher class than most devils, so it's not a stretch to think that she might consider herself socially superior to Ise, even though she loves him. Making her, less likely to be an easy servant.
