Well, her interest in adventure and the League was retconned out when the League became nonexistent. When the Universe site first began, that whole part about the League was absent from her bio page. If I remember correctly, her bio page simply had the whole, "Orianna loved to dance, but loses her life and Corin goes mad over it and reconstructs her."
I really phrased my thoughts... incorrectly? I didn't really know how to say it? I guess I miss less "Orianna's love of dance" and more... the symbolism and imagery that came with it. Orianna had always been the game's ballerina, its mechanical dancer. Now that image is kind of lost, and it becomes difficult to reconcile what's in game and what's in the lore (and I've seen the calls for a VU, but I feel that it almost removes her even more from the Orianna that was) What I also found interesting about the old lore was that Corin programmed dancing into her because not only was that an important part of the daughter that he was attempting to recreate, it also showed like... how he attempted to make her dance for him, like a wind up doll who doesn't quite know what to do outside of what they were made to. That even if she wasn't the Orianna that he loved when she was alive, that was fine because she was really created as a source of comfort for him, and continued to consider her his "perfect daughter". I understand that things change, but it's a little disappointing i guess.
