I like her. I know she's a bronze, and her SA isn't amazing... but she is a dark type (so no elemental weakness), and she's a filia (who I like), so she's pretty good in my book.
As with most filias, you want to make good use of her speed to rush attack and retreat before the enemy knows what hit 'em. Ringlet spire gives great battlefeild control once you get used to the pattern, and gregor samson can force the enemy backwards when you need more room to retreat for a skirmish.
Because she is a bronze, she is pretty cheap to bulk up on keys and slowly raise into a silver. And because she is dark, you don't need to worry as much about elemental penalties. I have her as a good all-around character, although windswept, parasite weave, and bad ms frosty do humble her comparitively weak special ability.
If you are good with filia, you'll find that bad hair day is a strong contender for high level bronze to mid level silver fighters: your enemies will be bleeding and dropping like flies in most cases... unless the character has immunity. then you may wamt to pick a character less dependant on bleed if you are unsure.
