As much as I dislike that "fake cuteness" loli, it has to be said that Burning Bush as far as abilities go is a pretty competent character.
I dont like her that much either, but credit where credit due, her skills are pretty solid as a support debuff 6*
But yeah it seems most of us got girls they didnt really want that much. Though there were lucky few who got really good girls they actually liked, so it seems the results were quite balanced in the end. And a free 6* is a free 6*
