Yeah, I more or less never posit my interpretations as Official Super Interpretations That Are Definitely Textual. My relationship to canon tends to be... aspirational, shall we say? xD I would like to run with canon as far as possible, but... man... I mean... I come from WoW. I'm maybe a little looser about smoothing things over with headcanon, and widening interpretation to allow for a greater freedom of roleplay, than most people would be. It was a sanity-preserving tactic back then, and it's hard to get out of the habit.
I'm in the lucky position that only a couple of my characters know anything about Ishgard apart from "it's cold", so I don't personally have to retcon anything, but man... I have friends who've worked really hard on making their characters believable and entertaining within previous dragoon lore, and it sucks if they have to scrap literal years of character development and roleplay and come up with a completely new character because of an arbitrary number from a piece of peripheral media.
