Personally, I kind of like the idea. I don't like hard coding voices based on race so much, but since so many people continually send tells when invisible and otherwise, it would be handy. Sure, if you can see most people it's usually just the Sylvans that show up as 'someone', but what if your detect invis fell, or you're blinded, or somehow stuck without light? In the confusing times when you have multiple 'someones' talking to you at once, it would be good to have some way to tell them apart, even if it's as simple as gender based or class based.

An etell like esay could be enough, if people used it.
