They meant to do it in 4.4, but pushed it back a patch. And gotta admit, while I knew it would happen, it hit me in the feels to see my offline friends list go from 500+ to 46 (including guildies). Maybe I should add more folks.
I do not have an answer, but I fortunately don’t seem to be having that issue. As mentioned in another thread, I am having difficulty unfriending people, such as trolls who add you to talk trash to you. You delete them, but I beleive the fried list mitigation is in a constant loop where it registered said user was my “Friend” before and keeps having them become my friend again when either of us log back in. Super frustrating!
