>>43587215>I don't think it's necessary to make rock resist itself since rocks themselves are used to break rocks. One of the main thoughts for that has always been "Rock types don't even take reduced damage from their own hazard"
>>grass resisting wind>I suppose this is because plants use the air for photosythesis, but all animals breath so they use it too. Strong winds destroy plants so maybe grass should not resist it, if anything just make grass super effective on wind.The logic for Wind resisting Rock/Ground/Grass was "types that are able to solidly hold their position on the ground, whether from just being heavy/sturdy, literally hiding inside the floor or attached to it via roots. Though Grass is still pretty much exposed to it, so your point is fair enough, but the other reason is that Grass can really use new resistances
>>sound effective against electric>>sound being weak to electricthe idea here was to add a unique two-sided weakness to the type chart, while referencing that the concepts involve similar formulas in physics (soundwaves/EM-waves, inetrference/resonance, amplification..)
>>sound effective against fightingthe Psy/Fight weakness to Sound was in both cases the assumption that both of those types are "skills" that rely on heavy concentration for offense/defense, which sudden disturbing sounds would break
>>rubber effective against water>i'd just make rubber only resist itI'm not gonna pretend that the main reason wasn't to nerf Water, but the apologetic I have is that Rubber offense is often about enveloping and constricting opponents
>>rubber being weak to darkRubbers Steel and Dark weakness represents Rubber getting pushed beyond the breaking point of its elasticity, whether by being cut by sharp metal or torn by aggressive use of teeth/claws etc.
>>cosmic being weak to poisonThat is a straight reference to war of the worlds, where the alien invasion eventually ends by the aliens not having an immune system adapted to Earth
