She's fine and balanced, imo. I can follow the same logic with every Kage rare too.
Let's take Darui for example : His high chase paralyzes 3 ninjas, he attacks twice with barrier on, his standard attack may cause paralyze, his mystery paralyzes hell a lot of people, he is a swordman so he can fit root teams and as root of warrior teams are going viral he fits well those kinds with his chakra nature and barrier :D

I saw people making a thread abt Darui saying so and asking to nerf him ... And, personally i find him quite useless myself.

I have all Kage rares and i find everyone too perfect for his meta, no complaints ! (except Onoki for now).

First, i wouldn't count them 4 because most of them are unceratin to happen.
1-Acupuncutre, only if she starts combo.
2-Poison, only if she wins the barrier.
3-Immobile, only if she does chase .. and she does't even chase her mystery. Now, people will say it's no problem you c*e an other ninja to link in --> cc that ninja and it's over :D

Second, 4 is just a number. Almost every ninjas has 3 passives/chases but some of em are useful and some of em are useless :D
