Quite different remark. I remember that we had a lot of colours, different for each faction. Knowledge of faction of player i met in locations brings in non PvP a more social aspect of a game. It was not only anonymous nick running around, but i knew and feel that char is played by person from faction with its history and unique relation between his and my own faction. NC gives little emotion: friendly, hostile, gratefull, angry. It gave us a chance to chat ingame about latest news, good trades, tricks..... In game, do you understand? Fonline needs a non PvP occasions to interact with players. Stay in city, talk, not only trolling.
It also gave us mumble/TS discussion topic: "why gang XY is at this location?", "did they found bug, new quest,...?". Anonymity of unknown nicks destorys a game experience.
Also uncoloured chars, when most of all were Ncoloured, was also reason and motivation to talk with "new" player/char, until you realized that it is another alt of well known players

So NC gives more, but unfortunately, it seems like you did not get that experience Jovanka. Fonline was and i hope it is not only about player vs. player interaction, but also about player vs. faction.
