I support this, as I've played many MMOs and they all had chat bubbles.

It makes dungeons and similar stuff easier because watching the chat log as a hawk in case you don't miss something can be really distracting, but with chat bubbles you don't have to take your eyes off of encounter. It's not a cluster and servers have nothing to do with it, your PC/console renders it.

Also just when you're sitting somewhere in game with someone and chatting, while trying to enjoy the scenery, but you can't because your eyes are peeled on the chat log, it gets annoying.

You have my vote. People who are against it are either deluded or haven't played any MMO prior to this.
