Let's Rework: Janna
Janna is a champion who obviously needs more skill expression and depth in her kit, so why not mini rework her to show that?
Passive (Tweaked) - Tailwind
Janna's air elemental, Tempy, grants allies moving towards it 8% movement speed. In addition, while it is orbiting Janna, she gains twice the bonus.
Q - Howling Gale (Changed) | 90 Mana | 14/13/12/11/10 Second Cooldown
Janna places a Whirlwind at her current location, charging it over a maximum 3 seconds. The whirlwind deals 60 / 85 / 110 / 135 / 160 (+ 35% AP) magic damage and knocks up for 0.75 seconds, increasing by 15 / 20 / 25 / 30 / 35 (+ 10% AP) damage and 0.25 second knockup duration per second it charged.
Howling Gale reduces the cooldown of Eye of the Storm by 40% if it hits an enemy champion.
W - Tempy (New) | 40/45/50/55/60 Mana | 10 Second Cooldown
Janna commands Tempy to fly to an enemy, dealing 80 / 130 / 180 / 230 / 280 (+ 50% AP) magic damage and slowing them by 40/45/50/55/60%, decaying over 2 seconds. Tempy then orbits that champion for up to 5 seconds.
E - Eye of the Storm (Tweaked) | 80/85/90/95/100 Mana | 16/15/14/13/12 Second Cooldown
Janna shields an enemy champion for 80 / 120 / 160 / 200 / 240 (+ 70% AP) damage for up to 5 seconds, granting them 10 / 17.5 / 25 / 32.5 / 40 (+ 10% AP) bonus attack damage while the shield holds.
Monsoon will cast from an ally's current location if they are shielded by Eye of the Storm instead of Janna, however, Janna will still have to channel it. Only one ally can be shielded at a time.
R - Monsoon (Tweaked) | 100 Mana | 150/130/110 Second Cooldown
Janna channels a powerful Monsoon over 3 seconds, knocking back all enemies and healing allies inside the area for 50 / 75 / 100 (+ 25% AP) every half second.
Monsoon will cast from an ally's current location if they are shielded by Eye of the Storm instead of Janna, however, Janna will still have to channel it.
