I think the valkirye is just too predictable in his fighting style. She has way too less useful chains in his moveset. They should add heavy light chain and a quicker heavy cancel with the shieldbash. Furthermore she needs a bit of love from the dev team so she becomes a valuable hero to play because now she is way too predictable and too easy to parry or deflect. Please let me know what you think about it because valkyries are the least played characters.
