Should more dual type moves exist? What about "Super Effective against this type too even though it normally isn't", like freeze dry?
Yes and yes
We would need more moves like freeze dry to counter new dual types

They definitely should.
Idk why this gen didn't introduced more moves like this.
Ice/Water types should be able to have scald but make it melt their ice type off like Burn Up.
>Insecticide
>Poison type
>This move is SE against bug types
because we need parasect to have more x4 weaknesses
