...there are lots of text on your screen already. Some echos seems nice but when implemented, it could clutter the screen and become more confusing without any benefits.

Imagine someone trying to call for help using group/cabal tell during a battle. You are along eastern road and running to him. The screen gets filled with lots of echos. Frustration comes in when you are trying to reach your friend, and yet each step is nothing but echos. The current yell for attacks, etc is fine with me.

The other concern is technically how far away should you be before you hear anything. 2 or 3 rooms?

The current natural echos are good for me and only the people in the room should see or hear anything.
