How to fix Azir's biggest problem

Obviously Riot doesn't understand that Azir's biggest problem is that his kit is way too damage orientated and about going in for a king meant to be having his soldiers attacking people and keep them off him.

His Q needs to have a low base damage and ratio, but it should enchance his soldiers AAs for hitting champs marked by his Q (with the slow). Azir's entire kit was made to be the long range high DPS who is weak to dives. The way his kit works right now is that he Q's AAs you to death so fast you cannot react or even fight back and even if you are a tank it doesn't really matter because he has the DPS to follow through.

Base HP 524 (lvl1) - 1884 (lvl 18) 1794(lvl 18) (to make focusing him later on a little bit easier)

Q - Damage - 65 / 85 / 105 / 125 / 145 (+ 50% AP) -> 50/65/90/105/120 (+ 25% AP) (taking the burst out of his kit)

W - Bonus AS 20 / 30 / 40 / 50 / 60% -> 5 / 15 / 25 / 35 / 45% (+ 4% for each 100 AP). This reduces his early game AS while leaving his late game at around what it is now.

R- Damage 150 / 225 / 300 (+ 60% AP) -> 100 / 200 / 300 (+ 70% AP) (about 40ish less damage at level 6). Each point in ult reduces the CD of Shurima's Legacy (Azir's passive) by 10s. These changes help solidify his role as a control DPS mage rather than a burst mage. His passive loses 30s CD in total at max rank meaning it let's him zone or push more easily later in the game to make up for his loss of burst.

Soldiers - damage 50 - 170 (based on level) (+ 60% AP) -> 60 - 200 (based on level) (+ 60% AP). This gives a little bit of his damage back early game, but it is more delayed and the reduced AS helps too.

I feel these changes would bring him back to his original late game monster self instead of leaving him a monster all game. His late game has always felt like it was the real point of him. Not chasing someone under tower at level 4 because of his insane burst, range, and dps.
