[2021] Buff Galeforce Yuumi

According to lolalytics.com, Galeforce Yuumi only has a 5% winrate, with a 0.04 pickrate. This is unacceptable. My theory is that Galeforce Yuumi is bad because Yuumi is unable to autoattack while untargetable, and has no AD, MS, or AS scalings. This problem can be easily fixed by giving Yuumi's W a new mechanic. This mechanic will allow yuumi to autoattack while untargetable. Since we do not want this mechanic to be overpowered, Yuumi's old passive, which restores mana, should be removed and replaced with a passive that does something like this: "Yuumi gains bonus attack speed based on how much mana she currently has, Additionally, every point of mana above 10 shall grant her 100 bonus maximum HP. Lastly, we should give yuumi extra scalings. Her Q now scales with 100% AP, and changes its scaling to 120%AD once it stays in flight for 1 second. Its speed is increased by 1% for every 5 MS Yuumi has. Her w has already been mentioned above. Her e skill now does 50 damage to her host and heals yuumi for 50+(0.7%AP+0.5AD). Yuumi can recast this ability within 3 seconds to deal half the amount she healed to every champion within yuumi's autoattack range. Lastly, Yuumi's ult does 100% of all on-hit effects, 150% AP, and 130%AD. She shoots out the line thingies for 3 seconds, and the frequency of the shots is 100% of yuumi's AS.

These buffs should fix all of the game's problems, and make Galeforce Yuumi viable again.
