By that logic, doesn't that make this list just as redundant as there's already the other list to go look at? It was there first.
Not necessarily, because this list categorizes by role, listing the most relevant (the
bosses) ones in a short and simple way. The other list is like extended reading going into further details, and sorted by player/character, not by role.
If you believe that your character should be listed here even if he's just say, a farmer, by all means post your character's name / player name and the role, and I will make it look pretty on the listing.
The reason the top roles are given preference is because those characters tend to stick around more than others. People make a new blacksmith every other day; but you don't get to make a new Temple high priest on a whim.
