This bug is mostly visible when getting hit by Black Prior's followup bash after light. I never have the ability to dodge the bash. I asked a few people on reddit and they said that guard switch recovery doesn't allow me to dodge, making my dodge 100ms later than it should. I dont know if this is an intended feature, but I mostly think it's more of a bug.
TL;DR Guard Switch recovery (100ms) delays the ability to dodge until those 100ms pass. The recovery time simple, but when every millisecond counts, it does get frustrating when the only reason we're getting punished by BP's followup bash is a simple mouse movement.
Hope this gets your attention.
