Why hasn't Patheon gotten reworked yet?

While I'm certainly aware other champs had issues, I do have to ask, why wasn't pantheon higher on the list? While I don't want to present him as perfect, Quinn top mains have nothing to worry about, he's got a lot going for him and in the matches he's good in, he's too good. As in the other player knows to play Soraka level passively or lose the lane even harder.

1. He's got a passive that allows him to ignore a number of AAs in laning phase and beyond. Since a lot of top champs are reliant on their AAs, 1/4th of the damage from autoing is gone. Unlike Sej's new passive, it resets while in combat.
2. His Q has a low mana cost and is spammable. Up top that means he can punish a lot of ranged champs consistently and they don't really have an answer to it. His Q is also just a click to use skill, no skill required.
3. Once he gets his E, his Q now has a good chance of finishing off a lane opponent with the extra burst its critical gives. If that doesn't work, his AAs also get 100% crit chance on low opponents.
4. His W gives him mobility, hard CC, and brings up his shield. As much as people hate Irelia's E, Patheon's W is far worse.
5. His E's active gives him a little wave clear, taking away another potential weakness.
6. His ult gives him extreme mobility, okay CC, and does a lot of damage on its own. With all the other advantages he has, this makes him extremely good at snowballing other lanes if he gets ahead.
7. He is relatively easy to play. LoG has him at a 56% win rate up top after 10 games. Champ.gg has him at 55% by 50 games.

So how would I fix him?

First - I'd change his passive so it gives 25 armor on the next AA you receive and scales by 25 every time you level your ult. Second is I'd make his Q a skill shot. Third, no stun on his W but it has a little bit longer range. Fourth is his E I think I'd lose the passive and the current AoE damage and make it a little more like Evelynn's E in that he gets a burst of damage and a few seconds of bonus attack speed.
