All it does is exist to be a filler weakness for shit, while Rock is both offensively and defensively versatile especially outside competitive where a very significant amount of the natdex is either weak to it or resisted by it. Also Flying has 3 weaknesses and is a common dualtype choice on top of being the single best neutral coverage typing in the game, taking away a weakness would be fucking retarded.
