She is viable only in arena with empress team together with mei and sailor sakura, but is not at all a meta team. In general i consider more useful the common hinata if is 5 stars, but it really depends on your other ninjas and main.

Just use her in arena if the missions require her, where 2 stars or 5 stars is the same.

You c*e her also with azure fang since her mystery will apply 3 times in a row poison with poison tai and healing tips make her 60% an 84% healing back (yes,is considered an healing except that it applies also when ignition is up), it also apply chaos and acupuncture with af's 3rd chase and neurotoxin (thing that the normal hinata doesn't do because her attack doesn't start the repulse to knockdown chase) so, they are a good duo, you need to add two more ninjas to make it work.
