I really don't like having to keep hitting "R" to talk with my friends, and I'd rather be able to talk to all of them with one command.
Which is why I'm posting this. The idea is that you have a friends chat channel so all your friends can talk with you, and if they're friends with one of your friends, they'll be able to talk with them too!
The only downside is that friendless people won't be able to use this. But adding this to the game makes it so much easier for people to talk with friends on a flash.
I think this was what Maplestory had a few years ago.
So much explaining when chatting about completely different things with completely different people.
