One of my biggest beefs with MMOs is the chat window. It is interesting how Ultima Online only had overhead chat bubbles. Of course, they made it "realistic" where you could only hear people nearby and you could whisper too, where people only heard a tile or two away.

This ended up forcing people to use 3rd party apps for long-distance chat.

Then Everquest brought back the chat window, and it was chat window only for a long time. CoX might have been the one that brought back overhead chat bubbles for local and team chat.

What I find annoying is that there has been no attempt to improve this method of communication. The more action the game is, the more the chat window fails to work. If some of the interface communication barriers were removed, I think MMOs might become more social. In the case of Champions, it is almost annoying to read their chat window for some reason.
