I think this would be a pretty neat idea to implement “buddy chat”. It’s function is basically exactly the same as all the other chat tabs such as Guild Chat, All Chat, etc. Buddy Chat will be strictly for all the buddies to chat into. I found this to be very effective in regards to the social aspect from games that I have played prior to GW2. Especially useful for players with friends that are spread out across different guilds and/or servers.
