The whole "ascians built in tempering into the summoning they taught to beast tribes and it's not actually a normal side effect of summoning" thing in EW.

Given the cases of spontaneuos or not-ritual-based summonings in the story (phoenix, susanoo, enkindu, etc.), I just find it hard to believe. It's true that we don't ever see any primals like these temper anyone, so it's not an outright plothole, but it's still strange that no one ever in history figured it out since summoning can happen accidentally.

It's not the only plothole in the game or anything, but it just rubs me the wrong way when it's dropped so casually and throws out a lot of thematic elements with summoning, and was clearly just written so that they can make a reference to the 1.0 trailer.

If this lore ever becomes relevant to the story in the future, I'll obviously just stop ignoring it.
