Reworked Shen W

So, I think it is a common opinion that Shen's W is the most lackluster part of his kit right? Well, with a Shen rework coming up, I thought I might post what I thought might be a cool idea for a new W.

Shen is the Eye of Twilight right? He is the ninja leader of the Kinkou Order who in the game is a Tank. So here is my idea for another type of defensive steroid, a unique one. A counter ability used to protect Shen and those around him with ninja-like reflexes.

NEW Ability 2- Ring of Protection Active: Shen begins to channel for up to 0.5 seconds. During this time, a ring quickly expands outwards from him. When a projectile from an enemy champion or enemy tower, or an enemy champion enters this ring, Shen will dash to the projectile or enemy. Shen is invisible while dashing, but is revealed upon ending the dash or the dash being interrupted. Enemy Projectile: Shen's ring freezes the projectiles until he has fully channeled or when an enemy champion enters the ring. Upon either of these events happening, Shen will extremely quickly dash to each of the projectiles frozen and deflect, completely nullifying them. This takes 0.25 seconds plus 0.125 seconds for every projectile to execute. While Shen is invisible while dashing, he leaves behind a blur while deflecting projectiles. Shen will stop the enemy champion first if they entered the ring, then stopping the frozen projectiles. Frozen projectiles cannot hit Shen's allies, but can hit Shen if they are detonated early by their caster. Enemy Champion: Shen dashes to the enemy champion, stunning them for 0.5 seconds and stopping any dashes unless they are unstoppable as well as shielding himself from 60/70/80/90/100% of the damage he takes while dashing to the target. Shen will then basic attack the target for 45/55/65/75/85% AD and applying Ki Strike if available. If Shen successfully dashes to the target, he regains 50% of the energy cost of this ability. If Shen is interrupted during this time, half of the cool down and energy cost of this ability are immediately refunded. Cost: 90/80/70/60/50 Energy Cool Down: 15/13.5/12/10.5/9 sec. Minimum (Beginning of Channel) Range: 200 Maximum (Fully Channeled) Range: 475/525/575/625/675

This way Shen is better at his role as a bodyguard of sorts while also being better at being a "Tank Ninja" AS WELL as having his W being quite satisfying. It should be really satisfying to see an allied Shen activate his W and deflect a wave of projectiles coming at you and then stop an enemy champion from attempting to assassinate you. This can also be combo'd with Shen's other abilities as well. If he tosses his Q on an enemy champion before activating this ability and they enter the ring, he will basic attack them and proc it. Shen can also dash to a target who enters the ring and then Shadow Dash through them easily without hardly any chance of them dodging unless they can remove crowd control. Thoughts?
