Ravel's tsundere personality only surfaced at the introduction of her character. But now, she's just a girl trying to compete for the love of Issei. No tsundere at all.

Anyways, Ravel will be just like Dante said, since Issei will be more useful in the battlefield than being stationary and addressing all the issues around. I'm not saying that Issei should leave all decision making to Ravel, but only pointing out and giving advice to what must be done.
