Hibari is good...VERY GOOD!!
Her AW stats are expected to be par with Cornellia (source:ULMF)...
Irrespective of what she gets as SkillAW or AW ability tommorow...She can 'easily' deliver an attack of 1.5K physical damage to upto 3 enemies at a time which can be very useful on many..MANY maps...
She has high Def as well so she can easily tank hard hitters too
