Agreed. He does rely on Ravel too much. I found it interesting where it was stated that most Kings probably couldn't use Ravel properly, and I'm still trying to figure out what that meant.

I suspect that Ravel is meant to critique and help innovate plans to help a leader develop rather than just make the plans herself. After all, if she does all the work for you, you don't improve. In short, she's nice to have to help develop your own skills as a leader, but only if you have the wisdom to recognize the value of that.

Issei is clever, problem is he is also rather simple. It would help if Ravel helps bring out more of a tactician in Issei, which in turn which make him much more effective overall.
