People who bring the real world logic behind the type chart to its logical conclusion are overthinking things. A lot of it is just based on stereotypes and cliches that you see in stories, some of them being particular to Japanese culture (like Bug defeating Dark types, because Kamen Rider is a bug and he fights evil). So yeah, you can drown a plant by pouring enough water on it, but people are far more likely to think about going out and watering your garden or something like that.
There are definitely some that I can't figure out as anything other than gameplay balance, though. The one that always comes to mind is Poison's weakness to Psychic. I guess maybe because Psychic is typically associated with mysticism, and thus healing?
>>39863546Well, Rock is also weak to Ground.
