Kog is the only Marksmen with his niche wholly tied to a longish cooldown
Every ADC has a pretty well defined niche at this point. They all use their longer cooldowns to support or augment that niche. And if their niche is tied to a skill with a longer cool-down, they either have a way to reset or reduce the cooldown on that skill.
Except Kog.
Kog'Maw is the only ADC who has no niche when his core skill is on cooldown. When his W is up, he's League's immobile machine-gun turret champion. When it's down, he's nothing.
Totally disregarding balance for a moment, if Kog is every go to feel fulfilling to play, he needs to always have access to his double attack speed/half damage effect by mid game at the absolute latest. There are many ways to accomplish this. His machine gun effect could be moved to his Passive and the self-destruct axed. W could scale down to zero cooldown, possibly with levels in his Ult shaving off the last few seconds. His W could be turned into a toggle. His W could have its cooldown refreshed on champion takedowns. Any of these could accomplish what Kog needs to be functional in different ways.
It's the only way Kog is going to ever feel decent to play without absolutely breaking him by just piling on more damage.
