I recently got Odette on DMM Aigis through the daily revival events but due to my low lvl wasn't able to farm a lot of her so she is only -1 CR for me. I wanted to adopt her as my new main mage over valerie. After using her though I am finding her not to be too great as you have mentioned above. Guess I will use Valerie till I can get another mage or Pallis as Odette just seems to costly at 35 before CC for me.
