Why has Graves still not been dealt with

I just feel like Graves has been in such a broken state since he rework and the release of and the buff that made his Q almost instant explode on walls. Why hasn't Riot dealt with his problems when he literally breaks the ADC archetype by being the tanky, huge burst, high dps, high sustain adc and has very few actually weak points.

I don't really understand his current kit. It is favored for both AAs and abilities which doesn't make sense. Also why does he get a stacking buff for armor and mr on a low CD ability that also allows him to skip a reload and acts as an AA reset. He can get armor and MR comparable to Leona on himself just by dashing and reloading. 10/15/20/25/30 that can stack 4 times on an ADC. Riot like c'mon what were you thinking. Even 10 flat across all levels is kind of ridiculous (1600g in defense available right at level 1 and about 4.8k at max rank on an ADC).

I look at graves and his current kit and I'm confused. He has the high base values of an early game champ, but he also has the scaling of a late game champ. He has yet to be polarized yet and Riot hasn't even dealt with it.

Seriously he needs something done. He can never ever be healthy and will always cause problems as long as his Q aas and e are all so powerful all at the same time. He isn't even punished for using the huge range on his ult. (80% damage isn't really that big of a drawback for how much extra range it gives).
