How can Kog compete against other Adcs?

Every time I face a Jinx, Corki, or a Vayne it feels like they excel at doing what Kog does only they do it way better. I don't even know what identity Riot wants to push on Kog because it feels like he is trying to fill 3 different niches, but isn't top of the dog pile in any of them. Vayne shreds tanks so much better than Kog, Jinx is the better late game carry and doesn't have her range modifier gated by a long cooldown, Corki brings a stronger magic damage influence to a team and overall better synergy with trinity force, and to top it all off they don't suffer from an absolute dog shit laning phase.

500 base range means you get creep blocked half the time you want last hit without your W. Kog can't follow ganks well he can't run away from ganks well. He can't poke with his ult anymore. Every other adc has decent Ad scaling on every ability and Kog is a complete slave to attack speed. How does Riot look at Kog and say "Yep this is fine everything is fine."

What does Kog do that other adcs can't besides explode when he dies? Is that the niche Riot wants him to fill shittiest passive on a Marksman? Clearly not because Kalista has him beat in that regard as well.

Edit: A common thing Im hearing is "OMG dat late game doe, but only if you are on a team with 4 supports who buff you constantly wipe your ass and hold your hand" and that argument really just goes for all marksmen. Teams should peel for their carries and amplify their damage when able. Kog is just special in that he gets dusted by a stiff breeze if you aren't protecting him.
