Many reaching Legendary rank lose motivation for further useful deeds.
The one who is motivated only by some new rank is on the wrong forum, because rank does not make anyone better or worse, some other things are much more important.
I understand that it is important for some to be prominent and different from others, whether they have earned 5000 or 10 000 merits, or made 100 000 good reports - but we do not need new ranks for that, each such member can get a special badge, maybe change the color of the coins below the name - and for those who have been on the forum for more than 10 years and have been active in the last 1 year, recognition could be given by adding the word
"veteran" to the profile.
