>>55399015>>55398959>>55398915Water rusting metal is a SLOW process that occurs over years. It is absolutely not representative of what happens in a typical Pokemon battle. (And don't @ me about how plants take years to erode rock or some such bullshit, grass types use magic to accelerate years of plant growth all at once. Not the same). Just spraying a Steel Type with water is not going to rust it during a Pokemon battle. And it's specifically SALT water that causes most rust anyway. Conversely, I do think any salt-based Pokemon attacks should do extra damage to Steel Types and certain Poison moves specifically described as "corrosive" should also fuck Steel Types up. But saying Steel should be weak to Water is dishonest, rust is a very slow thing that won't occur by simply splashing water on metal for 5 seconds.
>electric is strong against water because water conducts electricity>electric is not strong against steelThis is a misunderstanding of what conductive means. All it means is that things can more easily pass through a material. For water, electricity easily conducting through it doesn't harm the water itself in any way, and that's not what the Super Effective relationship is based on. It's based on how electricity IMMENSELY fucks up any living creature that's in contact with water during an electric strike.
The same doesn't really make sense for Steel Types because metal being electrically conductive can harm OR help you. The metal shell around airplanes and cares is why you are protected from lightning strikes. Because the metal is conductive, which means the electricity will prefer to travel through the metal rather than into your own body, and the electricity disperses harmlessly into the dirt. There's a very real argument to be made that Steel Types should RESIST Electric because if they get hit by lightning it will just conduct through them harmlessly.
