I'd like to see some physical fire moves added. After Fire Fang, Flareon's only option is Flare Blitz, so it has to hurt itself. Only things with Fists can get Fire Punch and very few pokemon get Heat Crash, so there aren't many options. Same for Electric. They've got Thunder Fang, then Wildcharge to hurt themselves with only select pokemon getting Thunderpunch in between.
I guess I'd like to see more...what would you call it...opposites? Physical moves for traditionally special type pokemon (Fire, Fairy, Electric, Ghost, and Psychic) while more Special moves for traditionally physical type pokemon (Rock, Special, Steel, and Fighting).
Other than that, I kind of like the variety we've got. Maybe some moves that cause environmental changes? Like a Fairy move that has a chance (equal to that of causing a status) to change the field to Misty Terrain, or an Electric move that does similar (but Electric Terrain, obviously).
