Yeah, that or I hope the difficulty eventually scales up as the game progresses. I assume there has to be a "hard mode" after beating the game though.There needs to be a hard mode on release
The changes I think I can tell from the beta are a longer parry window and almost no recovery on parries, which means more stamina, which means you can attack/Dodge and block more.
Also damage done seems higher and taken seems slightly reduce. The stun from Stamina drain seems to recover quicker also.
