We need to talk about ability cooldowns

There are two different types of ability cooldowns. The first kind is when the ability cooldown starts after the ability has finished, some examples are Nasus Q, Twitch Q, Garen Q, Darius W and there are others if you look and play, but you get what I mean. This is counterplay, you know exactly how long you have before they get that ability back off cooldown.

But then there is the other kind of ability cooldowns, the ones where the cooldowns start during the ability, some examples are Akali W, Kayle E, Illaoi E, Fizz E are there are others. It is a complete mess and offers no counterplay, it is unhealthy game design, that enemies cannot predict exactly when their abilities will be off cooldown, it doesn't offer them a proper window of vulnerability. But my complaints are, why does the ability cooldown start during the ability?

An Akali W at rank 1 is 18sec cooldown on paper, but technically it is 10sec because the thing lasts for 8seconds and the cooldown starts when the W is first pressed not when the shroud has ended. So tell me, why lie to players and write 18 seconds for when it is actually 10 seconds. Why not just write 10 second cooldown but make it start after the shroud has ended, why do you need to lie to players and make them feel like the cooldown is longer when it actually isn't.

Kayle, don't get me started with her. She takes full advantage of this ability cooldown mess. Did you know, at 38% cdr, she has permanent uptime on her E, and for a champion that stacks cdr anyway it is not hard to achieve this. Her E lasts for 12 seconds and the cooldown starts as soon as you press E not when the thing ended. Like wtf, she's a melee champion for fucks sake, not a ranged champion, allow her to become melee even if she has 40% cdr. What person at Riot thought this is a good idea?

My change to tackle this: Give abilities that take advantage of this ability cooldown mess a shorter cooldown not much, but make the cooldown start after the ability finished. So Kayle E as example, give it like a 3sec cooldown at 40% cdr rank 5 but make it start after the ability ended so enemies have 3 second window to exploit her while she is in melee form.
