Thought Experiment on exchanging R power budget to other abilities

Riot August talked about him wishing to readjust Shen's ability budget to have more combat in there, I thought of a few ways to adjust the active abilities. Not all changes are applied and not all abilities necessarily need to get changed

Possible R nerf:

  1. Less AP ratio

  2. Less % increase based on target missing health %

  3. Less Bonus HP scaling

Possible Q buff:

  1. Drag through on champion deals 3/4 of a strike's damage(minus total ad), each basic attack deals 3/4 of the current on hit bonus. The total is still the same.

  2. Q bonus damage now works on structures with a modifier

  3. Dragging through epic monsters also grants empowered attacks

Possible W buff:

  1. Applies Ki Barrier to non-self allies

  2. Provides a % damage reduction that scales with bonus HP but capped at a limit.

  3. Reflect the first basic attack damage to attacker for each ally champion affected

Possible E buff:

  1. Taunted enemy's aa deals less damage to Shen

  2. Longer E cooldown but taunting at least 1 champion refunds a cooldown that beats the current cooldown

  3. While taunted, enemies' damage to Shen's allies (splash damage like hydra or constant aoe like Shyvanna W) is redirected to Shen 100%

What do you guys think? Do you think any of those changes are too good to be true?
