New Lee Sin Identity- Anti-Tank Invader

I feel like Lee Sin's current identity of "Really good early, scales off late", is not the best identity and is too broad to be not hated when hes good and forgotten when hes bad. I think, with recent PBE changes shifting in the right direction, he should be shifted to become more of a Anti-Tank Assassin.

Passive

• Each attack now reduced the target's armor by 5/10/15 for 5 seconds, stacking twice for up to 10/20/30

Ability 1

• Base Damage reduced to 40/60/80/100/120 from 50/80/110/140/170
• Now deals 7/8/9/10/11% current health on the sonic wave and then 7/8/9/10/11% missing health on the kick
• Bonus AD Ratio reduced to 0.75 from 0.9

Ability 2

• Life Steal and Spell Vamp gained changed to 6/8/10/12/14% from 5/10/15/20/25%, being doubled in effectiveness now against champions and large monsters
• Now also gives 10/15/20/25/30 armor penetration to Lee Sin and his target

Ability 3

• Damage changed to Physical Damage
• Now ignores 25/35/45/55/65% of the enemy's armor
• Base Damage reduced to 30/60/90/120/150 from 60/95/130/165/200
• Now deals 8/9/10/11/12% of their max health as damage
• Bonus AD Ratio reduced to 0.75 from 1.0
• Movement Speed slow reduced to 15/20/25/30/35%, no longer decays
• Enemies hit by Cripple now also have the passive's armor reduction fully applied to them

This is a very early in process thing I rushed in my head, but I like the idea personally. Tell me your thoughts on this.
