It's a little odd how Cadence and Shining ended up having such a powerful baby. I see Cadence as the least powerful, when it comes to just bare magic and nothing helping out (Love, for instance) as the weakest Alicorn out of them. (I don't hate Cadence, I really enjoy her character, I simply see her as a little weaker than the others.) Shining himself doesn't seem all that strong when it comes to magic, so it's a little weird in my opinion that their child has that much power. They should have made it either a Unicorn or a Pegasus, their child never should have been an alicorn. That's just my opinion.
Babies never do much for a show either, they usually end up dragging it down. So much attention is showed towards them, and they usually end up just becoming blank, useless FOILs that only serve the purpose of showing how one character in the show is kind, sweet, loving, etc; or giving them some backround or roundness. Again, my opinion.
However if it wasn't Flurry who caused the storm, say it was Sombra or somepony, then Flurry's magic would simply be out of control; we wouldn't have a grasp on how powerful she is.
However again if it does turn out to be her, or she ends up solving the problem, then I see a need for her powers to be drastically reduced or to somehow be shown as being amplified by others means.
