This is pretty much a standard feature of ANY modern MMORPG. I probably won't continue playing past my free month if chat bubbles or at least overhead text has been implemented. It is a crucial feature for my style of play and pretty much necessary for any kind of social interaction between players. I can't understand how an MMORPG that is supposed to be the most modern doesn't have anything like that in the game at launch already.
its not a standard feature, in fact not many mmo's have this feature and thats a relief, bloody hate chat bubbles appearing everywhere. totaly no need for them.
