I played her and after getting the hang of her moves and combos, not only she's fun, but she reminds me a bit much of Hawkgirl except for her trait and powers. Once I'm able to purchase her next week (only bought standard edition), I'm gonna get better and understand more matchups between Kori and her opponents. Her trait is her best combo ender so far for keeping her opponent at certain range AND for a bit of pressure (plus sometimes interrupt another long range special, if used fast enough).
The only disappoint (mainly cuz of the VA strike) was for the fact that she should've had more dialogue interactions with former Titan comrade Cyborg (at least 5-6 different ones between each other), especially with the subject of Dick Grayson in the matter.
Speaking of Dick Grayson, a bit of intro dialogue between her, Jason (Red Hood) and Kara (Supergirl) about the former gave me a bit of tears. I hope NRS makes a new stage with Deadman making a cameo appearance in that one.
