Okay, I know that most of the players don't usually use it last year but since summer of 2014 the player count doubled and it will bring good use off the world chat - people can advertise their houses without standing at start and waiting for someone - the players can simply open world chat and go to their house or pm him
Another use of world chat is we can play games their like we do in the forums in the Entertainement section - and you can add a private group that a person hosts it and Invites other friends (not gang members) in the chat when the group is created a blue chat bubble will appear next to the chat/ gang chat bubble so it's easier to receive and send messages to others in the group chat - of course the host of the group chat will have powers ( btw the group chat lasts 1-2hours then it goes off then he has to pay for another 2 hours) the host will be allowed to remove a player from the group chat or color his chat or something...
Back to the main idea - I don't know if it will be useful for PK or not - but I do know that the players who are bored or who stick in start advertising their houses - prices : normal world message 1$ - group chat message /free but the creation of the group chat is 20$ - and each 1-2 hours to bring it back it auto takes 15$ -
Thanks for taking ur time reading
