I fully support this. I was just about to come and make a post about this. Chat bubbles already exist for NPCs, they look great, and they DO NOT AFFECT PERFORMANCE (which has been SQE's "excuse" for not implementing this). I don't understand why there isn't a toggle-able option for us players that really want this.

There is a huge disconnect when I'm trying to talk to someone and I can't LOOK at their character; instead I have to find their name in a chat window and interaction suddenly becomes a chat room, not an actual experience where I feel that I am interacting with a character in the game world.

Just implement this already. PLEASE. This is one of those things that would really make a huge difference to a lot of us.
