My reasoning to add this echo:
- The ability to mindspeak at very long distances is VERY powerful. It's more powerful than most of the spells available on FK. I think it is fair to have a "downside" to it, the downside being that you have to actually whisper your message into the amulet of communication. Note that, with that interpretation, what you communicate is sound, and thus "mental images" cannot be sent. Think of them as FK mobile phones!
- I know that this this echo means that the presence of hidden or invisible create can be detected. I am actually fine with this - this is not a bug -, and this is consistent with the fact that you have to whisper your message into the amulet. Does it mean that this change completely screwed up thieves and spies? Not at all... they can still perform well. The only difference is that they would have to move one room away before they can send a message discreetly.
- When you are talk with someone and that someone is busy thinking about something else, you notice it. I didn't like the fact that, when you talk with someone, you had no way to find out that they were communicating via their amulet with someone else at the same time. The new echo fixes this problem.
- If I had to answer the question "What is your number one pet peeve when you are roleplaying with someone?", I would definitely answer that what I hate the most is when people seem to not be paying attention to the roleplay. If someone is slow to answer, I can't help but think that they are actually typing in their IM windows at the same time, sharing information about the ongoing rp and getting OOC input from all their clique friends (and the same feeling is actually shared by many other players I have talked with). When the lag in answer is simply due to the person answering questions via their amulet of communication, this will be more obvious.
