*Spoilers* Anyone feel joining Emet would have been better

Not quite. The Lopporits say there will be a "tug" because of the sheer amount of aether, which means there's at least an effect and I think that can be associated to their different behavior before the summonings and how we know them in the modern sense. Then there's Emet-Selch who outright says he's tempered, using that exact word.

In other words, the writers wanted to try to get Hydaelyn off the hook despite the fact that they had already wrote themselves into a corner, so they gave a poor and vague explanation that we can deduce nothing from either way.
