[New Champion] Wise Old Qi Master Lady with Unique "Stance Set" Mechanic

There are currently no champion featuring wise old lady, and I would like to see one in the league. So I thought up a new champion idea that could fit this role.

The theme of Qi martial master from Ionia could fit the champion's image very well. She could even have interactions with Yi, Lee Sin, ninjas and more! We would love to see that happens!

I brainstormed a unique gameplay system that could become quite interesting too. I am not great at naming things though, so I will leave that to Riot's awesome creative team.

Here comes the meat --

Passive - Stance Set Every time a game start, she can choose one of three combat stance to play with:

1. melee, fighter stance
2. range, ADC stance
3. melee, tanky support stance

Each stance affects her stats and modify her skills:

1. fighter: grant bonus movement speed and HP
2. ADC: grant bonus attack speed and attack damage
3. tanky support: grant bonus armor and magic resist

Once a stance is set, she can no longer change her stance for the rest of the game. Think of the interesting scenario that could happen at champion pick, as each of these stances has very different playing mechanics!

Now here goes her skill ideas. Since she has 3 stances, her skills will have different effects based on what player chose.

Q - skillshot AOE projectile

1. fighter: punch to a target direction and send a blast that fans out and damage all enemies in short range
2. ADC: shoot a long range Qi that explode when hitting enemies, dealing AOE damage, similar to Karma's Q, but scales with AD
3. support: she stomp on ground sending shock wave in straight line that causes mini knock up and slow

W - buff target ally champion or herself, granting bonus stat and auto attack modifier for a few seconds

1. fighter: increase attack speed; grant lifesteal to auto attack
2. ADC: increase movement speed; auto attack apply slow
3. support: heal HP over buff duration; next attack will stun

E - medium range dash, like Shen's dash

1. fighter: dashing damages and knocks back enemies in the path; when colliding into enemy champion, the champion will be carried together with her (like Poppy, but will not stun when knocking wall), dealing increased damage and apply slow to the champion collided
2. ADC: can be casted twice in a row, mainly use for keeping distance or securing kill
3. support: while in the dash, she can "dissolve" AOE skill shot from enemy (works like Yasuo's wind wall, but trickier to pull off, her dash only last half a second!), can be used to protect herself and allies.

Finally, the most important skill, her ultimate! Ultimate should be consistent and easily recognizable, therefore it is the only skill that won't be modified by her passive.

I initially thought about giving her #tonsofdamage or AOE CC ultimate, but realized that there are already many champions who have these types of ultimate.

So I tinkered around a bit and found a gap!

R - AOE DEBUFF!

After an noncancelable brief channel, she apply debuff effect to enemy champions in target area, greatly reducing their AD, AP, armor and magic resist for a few seconds!

The only champion who has debuff ult is Trundle, and it is a single target spell. So her ult fill this gap of AOE debuff ult perfectly.

It deals no damage and does not apply CC, but when used at right time, it's game changing!

Okay, that's all the idea I have right now. I would really hope this wise old Qi master lady can turn into a reality and kick some ass in the league. Thought about this champion concept is welcome!
