Same, I Don't care if some kid says he's the champion of a region. Aloha has tradition that in game and in the anime that make pretty dam clear that they should be followed. Mike had to do it even though he was champion of Unova, but honestly if that's what the gm's want to do Azure, there's not a lot we can do.
I personally don't believe that the Totom Pokemon should be taken on one after the other since it prevents the Totom fighting at its best since it's still weak from before. It would be understandable if it was one challenge in the morning, one in the afternoon and then the other could appear in the afternoon and evening, then the Totom would get enough rest to get back to full strength.
