I agree the whole 'I know I'm gonna wear a revealing dress in the middle of a war to attract someone' has completely made any chance of them getting together as shallow as it can get.
I think she is good character, because her abilities are to heal and restore things not to fight.
The only thing I do not like is, that she is focusing to much on Ichigo. She should have noticed that Ichigo does not love her. He loves only Rukia.
