Aren't passives suppose to be unique

Ahri's whole passive is getting 20% movement speed if she hits a champion with 2 abilities. Akali is gonna be getting Ahri's 20% movement speed on her shroud ability, meanwhile still having a new and unique passive not yet seen on another champion. I have an issue with Ahri's whole passive being "x" but you give other champions "y+z+x" on one ability. But then Akali is still getting a really cool passive "p" that is gonna go with her class of champion and her style.

Other examples of passives: Ekko's passive is a 3 hit passive that isn't just autos and isn't super hard to proc. A simple e+q+aa will qualify to proc his passive bonus damage. Also Ekko will get at least 50% bonus movement speed. Issue here is Ekko's passive is "x" but better and has bonus damage on it. Zoe, gets a lichbane-like passive helping her weave extra damage hopefully into her combo, if she needs it. Zed's passive is doing more damage to you if you're below 50% health helping him to kill you and pop that ult death mark. There's way more examples to look at just not time. 

 I have no like hate on the champs I used as examples and I'm not trying to call any champ overloaded really. I just don't like that they are gonna keep this 20% movement as Ahri's -entire- passive, but then we just give out 20% movement speed for champion's abilities. They swapped the q movement speed with the old healing passive, the healing passive was unique, but it had bad scaling it was never very noticeable until decently into the game. You usually just see champions with passives they utilize at all stages of the game working with their entire kit. Ahri's passive doesn't do this, isn't unique, and champions that have movement speed on their passives are usually better number wise. (Or have the movement speed somewhere else in their kit)
A lot of assassins, mage or not, have some sort of passive to help them in their role wether its damage or some sort of property unique to them. If the extra movement speed really worked for Ahri and helped her do her job, you would see people nimbus cloak being taken on her. Which is a big issue for me, nimbus cloak can work with Ahri kit better than her actual passive. 

However, I'm against the idea that Ahri needs extra movement speed in her kit to flow better. What I really want to see is a new unique passive that goes with the kit better because at this point Akali's rework is gonna use Ahri's passive better than the fox ever could. Meanwhile Akali will still have a unique champion passive that also works with her kit, and overall goal as a champion.

(Not trying to say nimbus cloak is what you should take on Ahri but I noticed that it actually flows better with your ultimate gives more movement speed and all you sacrifice is either mana flow band or nullifying orb. Meanwhile Ahri's current passive is no where near as much movement speed and you sacrifice a whole champions passive...)
