Ik nuxias bad but...wtf

Im playing nuxia cause sum about her is just really interesting and want a character to play thats rarely seen but holy fuck shes bad. Im rep 6 and im getting guard broken WHILE swinging heavy attacks. Like explain how im already halfway through an attack and I just had a shugo and peacekeeper guard break me. She needs some elements added to her attacks like it should be change to position based- final heavys still hook but top does undodgable (but not a trap) and sides do unblockables that can be trapped. Like she needs sum cause shes to bare bones and can somehow be guard broken during her attacks
