I LOVE this game. Never experienced issues with blocking, guardbreaks, or parries like other people. Yes, the game needs more players, the matchmaking is unbalanced. But it tries at least. Super precise and fast paced, and I always loved games with executions (What can I say?). The issues seem to be PS only, because when I play on my XBox, it's fine, but when my friend plays, he complains that his guard was up.
Edit: Turns out he was using an assassin lol.
