Janna Mini-Rework Idea that addresses common complaints about her

Hello everyone, I am a Janna main (please note I am posting on a smurf account as i do not want people to op.gg my main account to criticize me for playing Janna) and this is what I would like to see as a more Skill focused Janna that improves upon her identity as a movement speed support without being an ADC Shield bot.

Base stats: Movement Speed: 320 -> 325

Passive: Instead of just gaining movement speed towards janna, Janna now creates a trail of wind behind her, Allies on the wind get increased Movement speed and a small amount of AD/AP (adaptive) if Janna stops moving, so does her wind trail. The stats gained from her passive scale with Janna's movement speed.

(Thoughts: this passive is much more impactful and actually noticeable, compared to Janna's current passive that I forget exists sometimes, It also emphasizes Janna's positioning more, and makes sure that she is constantly moving.)

Q: Mostly unchanged, but now the Tornado travels faster based on Janna's movement speed, and does bonus damage to slowed targets.

(Thoughts: I like her Q as it is, the Tornado Travelling faster and doing bonus damage to slowed targets allows it to combo with her W)

W: W Passive stays the same. W active is now a line skill shot that stops at the first enemy hit, Allies that her W travels through gain a small shield and movement speed, the enemy it hits takes damage and is slowed, the amount slowed scales on both AP and movement speed, the damage would be about the same as her current W, If her W hits an enemy Champion W's cooldown is reduced.

(Thoughts: A lot of complaints about Janna is that her W is a point and click undodgeable harass in lane, so by making it a skillshot it allows some counterplay, however now it will be more impactful if it does hit, since the slow will be greater, and it also benefits allies since this will be her new shielding ability, similar to lux's shield.)

E: Janna gives herself and her nearest Ally bonus movement speed for up to 3 seconds, this movement speed breaks upon Janna entering combat making Janna and her Ally's next basic attack do bonus magic damage based on Janna's AP and Movement Speed, the bonus damage can be hit on a tower.

(Thoughts: This will be Janna's new main agression tool in lane, and allows her to roam better and can allow an Ally to escape with the movement speed if Janna does not enter combat, notice that this is no longer a shielding ability and no longer gives bonus AD, as those have been transfered to her W and Passive.)

R: Janna gives an Ally a very large shield that lasts for a long time, Shield health scales on Janna's AP and movement speed. Janna can detonate the shield after 1 Second to summon a monsoon at her shielded ally's location knocking all enemies back and healing allies over time, heal scales on Janna's AP and movement speed.

(Thoughts: This combines Janna's old E and R into one ability, meaning that Janna's only big shield has a very long cooldown, this also means she has to be more careful about who she shields, as well as her ally's placement and her monsoon's location.)

Overall Thoughts: This will make Janna more focused on movement speed and buffing her whole team, rather than just making her an ADC Shield bot, as well as greatly increasing Janna's skill floor and cieling. Also notice that there are no actual numbers on the post. This is because i do not know how to balance numbers, maybe you guys can help me with that. Please give your feedback. Thanks!
