>>56050380rock's resistances are WHY it's bad. three out of its four resists are shared with steel, who also resists SEVEN other types. anything but fire? use a steel type. fire? water exists and is a high-tier type.
two out of its four weaknesses also overlap with steel, with one also being resisted by steel, so it's not like you even get those scarce few resists with the tradeoff of entirely different weaknesses either.
on the offensive side, rock moves are also near-universally bad stab options due to their low accuracy. for everything that's not iron boulder or cornerpon (the only two good offensive rock types lmao), they're either swinging with a shadow claw-tier move or they're constantly missing and failing to kill things they should. rock is good coverage because turning losing matchups into ones you win (most of the time) is good, but as a main stab it sucks ass because it just fails to do its job quite often.
