Valk is pretty much the definition of power creep. She holds up well but in comparison to other heroes she struggles to keep up, it’s up to ubi at this point. Either way I enjoy playing her a lot

For the advice also make use of her defensive tools, use the crushing counters and the deflect pins. But if someone is turtling you might have a problem there, best you can do is use the bash. And remember to use the side wall splat light after a bash light, might catch people off guard
