I've had some people parry some really obscure weapon arts and I don't even know how people figured out the correct timing for the windows on that, considering the issue I keep getting with latency. I've done quite a lot by now, and the one problem I still have is dealing with parries - both in performing, and being performed on. I show that I have it, flex it a bit and it makes someone more cautious about directly attacking me. So I've been doing some PvP and I notice a few people use the caestus, which I've only ever used for pressure.
