What lore do you ignore?

[Iscah]

That might be because I come from a roleplaying background, though; outside of concessions to allow for the fact we're all playing the same story, I find it's really important that everyone is on the same page about the common setting they're in.

If you're dealing with other people then yes, but at the same time you can have a private concept of it happening differently.

Maybe it feels different with RP since that's closer-knit into your character concept in the first place, but for discussing lore here I will stick to the canon version, while personally noting that there are some things that wouldn't have gone that way if I was creating this story for my character(s).

I think the only thing that I may come close to ‘ignoring’ is how much time has passed since ARR and Endwalker. I seem to remember someone on the creative team saying its only been like a year or so

I've never seen the original source for that quote, but I suspect it may be a misquoted statement on the concept that the game occurs in a year-long time bubble (it will never move past "five years since the Calamity", however implausible) which can fit any number of years of activities into that bubble of calendar time.

It is also at least a few expansions old, so they might not even try to claim that any more.
