erase bug and end its suffering
In all honesty, I find it really weird that Bug is a type at all. Most other types obviously correspond to certain elements, so that they can be applied to both moves and Pokémon, while Bug is just...Bug? Sure, Bug-type Pokémon make sense, as well as giving them weaknesses and resistances other types don't have, but... Bug-type moves feel a little unintuitive, and it's not like Bug is an offensively great type either. Like, what would change, really, if Bug was removed as a type? Grass gets one less weakness (thank god), types that already resist Bug aren't affected much, Fire and Rock remain offensively potent types (and Stealth Rock isn't that unbearable anymore, though maybe you could buff Flying, idk), and Psychic and Dark still have other weaknesses to worry about, so it's not like removing Bug would shake up the metagame that horribly, especially since it's not that competitively popular a type.
