I ran into a valkyrie main today and she was complaining that her up guard was broken. I thought she was just being silly and mistiming parries or something along those lines. She said she wasn't. She said she wasn't talking about chip damage, either. So i asked her if i could test it with her and we began a test of me, as warden, spamming top light attacks.

She put her guard in the up position and then let go of her controller and i just spammed away. I went into exhaustion twice but the third set of blows, something peculiar happened. A light attack did get through. She started the animation where she went to block the attack but then it just went through. Ill record it when i have the time and bring the video here, but it is very peculiar and i wonder if it affects other heroes/block stances. the side blocks seemed fine, tho. only the up block.
