Parry is monumental when your evasion fails. You literally negate the damage done, which means you can negate any weapon swing, including big skull crushing moves from NM's too. The reason Parry is often ignored is because people don't have it skilled, meaning it rarely, if ever, procs. Mine is now proccing 1/5 swings on my THF/DNC, and getting faster too. It's great to see you deflect an attack with your own weapons. It is very noticably improved.
