Take me for an example, I always add healers and tanks i raid with as well as friends' alts to my friend list.
It would be amazing to have such a list on all my characters and it would be as easy as click a button and maybe a confirmation as well to import a friend list from another character in my legacy.
I feel like an hermit time? I just click off the chat or ignore those who whisper me until I feel friendly again.
Sorry, can't make much sense out of what you are talking.
