I think a solution to this would be to extend the hit boxes of the shadow counters closer to the character that is using this so this can’t be an option for Fulgore. We’re giving up a bar to punish him for our read.
I’ve done some work and looked into who can do it. Much like how Infil’s pic of Fulgore vs. Fulgore works, the attack hit box of the Shadow Counter cannot reach the attack hit box of the dp for some characters.
Personally, I think this is a fair adjustment.
