Counterpoint: "dual type" moves should never be a thing again.
They're both counterintuitive and a mess to mentally figure what they're supereffective against.
Ironically, Flying Press is basically hurt by its "dual type" as it's not supereffective against the things you'd want your fighting stab to be supereffective against, like Steel or Fighting, and thus noone would ever run it.
I rather them do more stuff like Freeze Dry, which is by all means a Ice type attack, with the single extra benefit of changing one type interaction.
If you want a fancier Heat Wave, it could have been a Flying Type with the added perk "It's supereffective against Steel Types", I guess. That'd be easier to memorize than a dual type.
While I would like to see more Move's like Freeze-Dry (if I were to suggest one, a Fighting-type move called "Spirit Punch" that is SE against Ghost and neutral against Fairy & Psychic), I don't think the "Dual Type" moves are a bad idea... just now the way Flying Press works.
Having it have it's own Type Chart is just confusing, I think it would work better if it was one Type or the other depending on the situation. I see it working in two ways:
- It picks the Type that would be the most effective against the target (if both are equal than it defaults to Fighting).
- It first applies the Fighting-type, but if the Fighting-type is resisted/immune, it checks to see if the Flying-type would work better. If it is, it becomes Flying-type, if not, remains Fighting-type.
For balance I would say the second option would be the best as it'll keep Flying Press from being too much of a two-in-one Move (which is probably why they did the weird combination idea). In addition, this would allow easier creation of other "Dual-type" Moves as now they don't have to worry about the Types being too counteractive with each other.
I think I'm a proponent of radically replacing the Flying-type with a Wind-type, turning most of the "bird" moves into Normal-type, and then make Flying/Levitating into some sort of inherent trait, visually signified by whether it touches the ground in battle. Intuitive. And then Roost, Gravity, Magnet Rise, Smack Down, and Thousand Arrows change the idle to a more appropriate one while in effect.
Hm, I just want Flying-types to have more general options, not completely revamp it.
And I feel giving a Pokemon a trait that would have an effect in battle based merely on design is a dangerous road to go down if not handled with care.
Which Move would it be an expy of? Sounds like just a direct attacking move, so either Hyper Voice or Liquidation, depending on whether its Special or Physical.
