I really, REALLY hope they'll consider this.

Not only would I be WAY more inclined to spend time playing multiple characters, but also, it would just be nice to not have to worry about "Well I started the game playing Character#1, I've already started playing Character#2, but now I have to juggle which character has done which things, which items they attained that other cannot, etc".

It would be such a godsend to be able to enjoy the game on multiple characters. Even if they have to be max-level, as another player suggested, before they can become "linked". It's obviously been YEARS since ARR was in session, but I did quite a lot with this character. I have begun playing a new Au Ra character, and it's been a CONSTANT series of bummers to have to juggle "what stuff have I done on which character, and is it worth bothering trying to complete the same content multiple times?". And you know, I really want to try a Hrothgar when they come out, but is it just going to be the same problem? I'm already really liking my Au Ra, and I don't want to "lose" him just because I want to play as the Hrothgar when they release.
