Originally, reputation was used as an honour system to indicate how much we like a player or how we feel about them. Now that the reputation system has actual in game mechanics, it often feels like a currency that you can spend. It no longer really reflects anything about the player and seems to be over used. I would propose to bring back the old behaviour as a new system and call it honour. The honour system would be the only one that colours a person's name in chat and in the popups. Regular reputation would not change beyond that. The honour system would not have any in game mechanics beyond name colour.
