I vote no.
I have little desire tp chat with my Friends. I have no desire to chat with Friends of my Friends that I have nothing in common with.
Note that global, Guild, and hood all have a uniform makeup. Everyone in each of those groups has the same peopke in each of those groups.
Each Freinds list is different from every other in the world. How exactly does this limit? Is it a chat channel that only my Friends can join? If so, doesn't that equate to INNO providing a chat channel for every person in every world?
If my Friend's Friends join the chat it'll eventually concatenate to pretty much the world in that chat room. We already have Global Chat.
