I have her benched as well, and she's still only lvl 10 (since I also got a dupe along the way). However, I do keep her in mind, incase I ever want to make a vampire squad, maybe in combination with some ability trigger unit(s). Let's just hope her bloomed form will improve her +ATK on skilltrigger bonus, so she gets a little bit closer to Fritillaria in that regard. As it is now, it's nearly useless.
