Janna rework

Janna: Wandering Wind

P: Stormy Sorcery
Janna gains additional maximum mana whenever she damages an enemy champion with an ability. Janna gains bonus movement speed and her allies gain bonus movement speed moving towards her based on her current Mana.

Q: Gathering gales
Janna begins to create a tornado at the target location. For the next 2.5 seconds, Janna can create a second tornado as well. 5 seconds after the initial cast, or upon recasting the ability after the 2.5 second window to cast the second tornado, the tornadoes will both fly towards the cursor, damaging and knocking enemies up and slightly back. Distance, damage and knock up duration all scale with charge time.

Janna cannot place the second tornado within a certain proximity to the first, and both tornadoes have an individual Mana cost. At maximum rank, Janna can create a third tornado which also cannot be within a certain proximity of either previous tornado. It too has its own Mana cost. Charging tornadoes will be pushed along by Slip stream.

W: slip stream
Janna creates a wind tunnel on the map. Allies walking in the direction the wind is going go faster, while allies walking against the wind go slower. Allies standing still move slowly in the wind's direction.

After emerging out of the wind tunnel Janna and her allies deal bonus damage for a short duration, which scales with how long they were in the tunnel. There is a minimum amount of time necessary to spend in the tunnel before being given the bonus damage buff at all, and they must be moving with the wind.

Slip stream operates on a stock system.

E: Eye of the Storm
Janna creates a hurricane at the target location, granting her vision of the center of the storm. Allies in the Eye of the Storm receive a shield, while enemies take damage over time and are slowed if they stand in the outer perimeter. If an ally leaves the storm they lose the shield instantly, and cannot regain it by entering the center again.

Eye of the Storm will be slowly pushed along by Slip stream.

R: Monsoon
Janna creates a Monsoon that is perpetually in effect so long as she is alive. The storm is directed to the target location either by pressing R or alt+RMB. Allies inside the monsoon are healed by the wind and rain, the heal getting progressively weaker with each successive second they remain in the storm, down to a minimum of zero. The monsoon regains it's potency after having gone a period without healing anyone. The monsoon's healing potency is greatly reduced if it is too close to Janna herself. The Monsoon's travel time is affected by slipstream, and will do minor damage to enemies caught in it if it meets the conditions to receive slipstream's damage buff.
