Again, how did Midgardsormr blow away our Blessing of Light just like that if it's our being tempered?

Also, at what point of Shadowbringers before we blasted Emet-Selch away did he work against the interest of Zodiark? Everything he was doing was trying to bring the First closer to ruin in order to bring a Calamity and in one timeline where we weren't present, he succeeded. Since he's got the ability to see people's aether, he could have also at any point of time just casually dropped that we were tempered by Hydaelyn in order to mess us up but he never did and spent the entire first part of the expansion trying to schmooze with us and convince us, or at least any part of Azem inside us that he's right. Why would he even try if he could tell we were tempered?

Also, to be tempered you need to be in the presence of the primal. Venat and her crowd weren't tempered by Zodiark at the time he was the Will of the Star, why would Hydaelyn be any different, especially when she's weaker? We're not face to face with her outside of visions until late in Heavensward, which would invalidate any examples of so-called tempering before that event. And if she could temper people remotely, then why doesn't she give everyone on the entire planet low-level tempering? That would prevent literally every single Calamity that has ever happened if she says "free will for all, except in case of emergencies".

Tempering itself is a very weak narrative tool that already had its moment in the story in ARR and now it's being invalidated with the events of Shadowbringers anyway. I don't see any support for us being tempered beyond suppositions or misunderstandings.
