The table is headed "Locks", not "Player Level". Heroic tier locks have an Open DC of 20, Paragon tier locks have an Open DC of 30, etc.
So it doesn't mention lock quality at all in the table or descriptive text...right? Again if I walk up to someone on the street and state I have a "paragon" quality lock that means... what exactly? Why not just state it as a mediocre, average and superb "quality" lock? In other words why use heroic, paragon and epic? How are using these descriptors in any way intuitive if it has nothing to do with using the number based on the actual tier a player's character is at?
