I used in the last Forging Bonds to get her some HM and found I really like her. She just has a speed refine on her Wo Dao and Swordbreaker but she was very reliable.
Her Spd is fine, and even more than that. The problem is people try to build her as if she were Ayra, and ends up being a worse version than that and about everyone else.
I agree Swordbreaker is probably her best budget option. She doubles pretty consistently beyond speedy swords, and this helps her avoid and double them.
