I agree. Perhaps they should make an Ability that is like making them part Flying in a way. They don't have the weaknesses or resistances of a Flying-type, but they fly like one. It can be called something like Airborne. All it is is an Ability that allows them to fly with wings.IMO, levitate should be given to Pokemon that can, well, levitate. Flygon actually has to move its wings to fly, which shows that it doesn't levitate, but flys instead. However, Pokemon such as Solrock do levitate, and it's obvious that it does. I think Flygon should be a flying type, even though it's type combination is unique.
Do you guys think a bigger emphasis on the evasion ability of flying Pokemon will give them a better edge in compeditive battling? I've been talking to another person who apparently battles comparatively and she says that everything flying types do, another type will do better. For example, against Grass types, a well-placed flamethrower will do more damage than another comparable flying type move.
So I've been thinking if flying were to be a defensive element primarily and thus have flyers rely on their other element to deal damage.
