There won't be any difference between experienced players and newbies. All of us will have to ask NPCs about their name, in case this feature will apply, that is. Yes, they might know some of the NPCs, if not most of them, but is that really an advantage? What would be the problem for a newbie to ask any NPC he sees about their name? I personally don't see any problem. Plus, new players are that way encouraged to get into chat with NPCs, so they will probably learn about the conversation with NPCs faster. Probably.
And, if you are looking for a certain NPC, which happens to be located in BD, what's the advantage for an experienced player - who knows about his location - before and after the change? It all comes down to traveling. Experienced players have traveled to the BD, hence they know most of the NPCs around there, and as soon as a newbie has traveled to the BD, he will aswell.
However, with your complaint about the experienced players you were going a little off topic, but I see where you were coming from. Nevertheless, and although I often help new players getting along, there is a player guide available, and the server MOTD suggests everyone to read it. If only 30% of the new players would take the time and heed the advice, there would be much less frustration on both sides. Don't you think it is a little selfish from a newb to enter a game, not to say a MMORPG, and expect other players to help with every little booboo they have, just because they didn't want to spend 5 minutes reading the guide?
I help in most cases, but not everyone is as patient as I am, understandably.
