the only global chat i can think of that doesnt get abused and IF people get banned faster then they can think was EVE,
every other mmo ive seen, global chat was meeting of the primitive trolls usually, and it didnt add anything to the game, people usually didnt help, they rather laughed at other people...
The problem is... most people just disable it and the new players and assholes stay in it to "express themselves". - there might be exceptions ofc -
There can be so many ways finding a linkshell or other people.
- proper party system
- linkshell recruiting menu - NOT simple a channel - something where linkshell leaders post their website, their goals, if they are casual, hardcore whatever... endgame focused etc. etc. and you can apply . i like that idea more then a stupid global chat that has no real purpose.
the worst global chat i can think of was aion....
