Electric:
SE on water
nothing on steel.
why?
If electric is SE cause water is conductive than it should be SE on steel. If steel is neutral because it's a conductor than why isn't water neutral?
Also Ice should be SE on water, freezing water is simple and kills aquatic life.
Also ghost, why doesn't it get resists/immunities to all physical elements (fighting, steel, rock, ground, flying, grass, etc) and get fucked up by energy attacks (ghost, electric, fire, fairy, etc)
There is so much more.
