What i mean is there is no reason for them to exist.

Flying: Moves that use Wing, beaks or other bird based actions (Roost, Peck, Wing attack, Aerial Ace). Wind: Moves that use the air, dosen't matter how they are produced. (Air Cutter, Gust, Whirlwind, Hurricane)

Psychic: Mind based abilities (Psychic, Psybeam, Hypnosis, Teleport). Light: Photon based abilities, no similer properties (Luster Purge, Doom Desire, Flash cannon, Flash)

Sound based moves are only classed a normal because a sound type does not yet exist and they do not fit anyother type.

Reason for existance? Increased type variety, more accurate pokemon typing (Tornadus Based on fuujin, God of wind.  Wismur Evo line, prominent sound based pokemon)
