Not sure if it's possible or not to implement one, but I am curious as to whether some type of chat platform / program can be integrated within the game. Like "Real ID" or "Battle.Net" but a version that you guys develop and maintain. I'm thinking it would probably work out pretty well with the whole cross-realm activities, battlegrounds, dungeons, social events. Is this something that will be considered? Has this already been attempted? Looking forward to any and all feedback. Thanks!
Too much work for too little gain.
It is possible, it would take a lot of work, and guilds already use discord which has way more features than wow chat.
