I had a very bad falling out with a former friend who I played FFXIV with (hopefully she doesn't read these forums lol!), and I blacklisted her.

Then, I decided to world transfer, to play with other friends. I didn't anticipate that I wouldn't be able to re-add her to my blacklist, as the player search is only on your own world. Blacklisting her hadn't even removed her from my friend list! It was a nasty surprise to click on all of those Cannot Retrieves on my friend list and seeing her, and online no less.

She knows my character name through a mutual friend. I really, really wish that I could blacklist her and reduce the chance that I will run into her on party finder randomly. I can't even be sure that she won't see my character name if I create a party.

I understand that this is a niche concern, but if the devs want to expand cross world functionality, there should really be a way to blacklist someone on a different world without having to interact with them first.
