I think the parry system works fine but once you get use to the controls it's to simple. Rather than having 4 quadrants to block L.head R.head L.body R.body they should have body L+R Chest l+r and head l+r gives you two more attacking options and therefore rather than 1 out of 4 for the parry it's 1 out of 6..not easy to do.I think that would sort the problem and still have an effective way of blocking.
