I think we should have an additional four extra usergroups. Or 3, not sure.
An "Airbending Master" usergroup.
"Earthbending Master"
"Firebending Master"
"Waterbending Master"
Each person should be chosen very wisely for the position, and should be automatically risen to Elite rank for roleplaying purposes.
That way we have those who can teach others how to bend more efficiently.
And, once a master clarifies that a student has been taught, their rank should be risen to 150 (Advanced).
As well with the Firelord, Tribal Chief, Avatar, and Earth King, our ranks should be risen to Elite as well. There is no such thing as a weak leader, is there? Not in the world of avatar, in my opinion.
Thank you for viewing my suggestion.
