A couple different things have happened with this since the recent update.
First, we would run into a situation where our puller would grab the NM in question with some kind of magic spell, and their Abyssite of Discernment would give them a message for what element of magic is required to get yellow !! weakness. Shortly into the fight, the same person, or another person using a Discernment Abyssite, will get the message again, but the element is now different. When this happens, the latter element is always the correct one. We just occasionally get an incorrect message on whatever spell was used to claim.
Then, we had a situation where everyone was seeing Earth as the element to required to get yellow !! weakness, and then our ninja cast Kurayami: Ni (which is Darkness), and the game said he was the one that landed the weakness. We reviewed our logs and it was the only spell he cast within 2 minutes in either direction, so it wasn't a lag issue. At the same time, a Blue Mage did cast Magnetite Cloud, and they both appeared to have gone off at the same time, so perhaps that is a "the game reported the wrong name" issue, rather than the Discernment Abyssite giving bad info.
