Her attack can't be dodged easily, if at all unless she lets you or you're much faster than her. The sharingan allows her to fine tune her attack so she can adjust as needed if you try to dodge. Also, the technique is simply a strength enhancer... All it means is whichever fighting style she uses, she will have the ability to rupture internal organs with relative ease.
Ontop of that, she has the potential to be the first uchiha to differ from the norm. Kishi can develop her as a watered down amalgamate between hashi and madara, or turn her into the strongest 3-tomoe uchiha in history. She can have a Senju/Uzumaki based fighting style which is supported by sharingan abilities, or an uchiha based fighting style complemented by bijuu level chakra and healing (if she learns byakugo under sakura's tutelage). She even has the potential to develop completely differently from the fighting style we've currently seen by using a fighting style adapted from both sakura and sasuke. let's be honest, she's already copied sasuke's fighting style because she had her sharingan on while he fought...
