One problem with the character names is that it is very hard to figure out who is who especially if each person’s characters have a unique name. In the guild window it shows only the name they signed up as and if they are currently playing it shows the current character’s name as well. But this is really cumbersome. You look in your guild and it is like “who is that person… oh I think that’s also so and so.. is that the same person as the one I played with yesterday…maybe I think he is also has a monk but I don’t remember the monk's name…”

I suggest an option of creating an account name. This account name would always show up as your name in the guild. That way every one (account) would have one name and it would be much easier to get to know who is who in the guild. Another thing you could do is when you mouse over this account name it would show all the characters on that account and their classes.
