I've been struggling with counters not landing this week too, been wondering if it's a PS specific issue. 1H Focused Blast seems the worst. It should be vulnerable to interrupt but the lunges just don't connect sometimes. It's very frustrating to die to a pair of people who just spam that move while lunging away does nothing. I don't think anything actually changed from the update though. The occasional counter not landing just wasn't a big deal before. Now that damage is harder to come by any missed counters matter.
