Allow me to complain about something completely different: Freeze-Dry and Flying Press.
When these moves were first seen three years ago, we were dumbstruck. A dual-type move had never been seen before. And Freeze-Dry makes an exception to the conventions of the type chart. This was something new and different! But... wait, there's only one dual-type move, and one typechart-exception move? Oh well, perhaps they'll make more in ORAS. Or in Z. Or, at the very least, in Gen VII.
But here we are, and the two different, unique "concept moves" remain at the concept stage. To my knowledge, there are no new moves with dual typing, and no new moves hitting for off-type-chart damage. Those were very interesting concepts, each with many great opportunities, but for some strange reason Game Freak chose not to progress with either of them.
Oh well. It's not the first time they've done so. I still lament the loss of dynamic music after Gen V.
