Yes I know this has been suggested before, but what I am suggesting is a little bit different. It would be cool if we made speaking and whispering a little more realistic. When someone speaks, anyone in a range of lets say (arbitrary) 15m can hear the convo. Anyone outside of this range will not be able to see the convo. Now as for whispering, you would do the same thing but at a much smaller range (2m). No one outside of 2m can hear the convo, however anyone (i mean anyone) inside of the area would be able to hear the convo.
How would this be more realistic? Well we aren't telepathic, and back in the 1500s there weren't any walkie talkies/cell phones or what not, so anyone sharing secrets would have to talk close to one another. And in game you would see someone say, lets go here so no one can hear us etc... Plus being a spy will be a little harder cuz you have to get close to talk and others can possibly hear you so you would have to watch out.
I'm completely against this idea. If my friend is working on a sky bridge on the other side of the map, And I am building a giant megaman sprite, I don't want to have to get into a small little house with him so we can make lame cock jokes.
I suppose this would be cool for a goal based game like survival. Talking there would consist of making plans, Not just chit chatting.
I meant this idea in terms of survival. I would hate it as well if this was on creative. And creative isn't necessarily supposed to be realistic anyhow.
As for global chat, I dont think it should be eliminated completely but rather severly limited. Maybe, there is a long delay in recieving the message. Like a letter for example. <Craft a mailbox and check it once in a while. Something like that.
