>>42009013>Nah, on my side I still struggle with Rock NOT being immune to Electric, only because encountering Rock types in ingame battles that weren't fucking Geodude/Gravellers/Onix prior to Gen ~4 felt so fucking rare that it never clicked.aerodactyl, omanyte, kabuto, omastar, and kabutops were rock types that took super effective damage from electric attacks.
having type weak and another type supereffective is also not an excuse, since there are many examples of this showing clearly that ineffective moves win this (aerodactyl's first type being weak to earthquake but second type immune = immune; charizard's first type being weak but second type being immune to earthquake = immune).
there's no real reason why rock types should be weak to electric attacks, either.
