I was IN the raid and listened to the party leader mention the tells they were getting. I have no clue what was said to you, but I know what was said to the party (voice) and what the party ended up accepting into the group for completion. He accepted a 20/wiz - which was obviously not a water savant, so I think it was more about spell DC's vs. requiring a water savant. Again, not that I care to debate that argument, just telling you what I got to listen to while in the group while we filled and as the caster made the run out to the quest.
