Shen Rework Concept
Besides for remaining as a Ninja Tank with a Global shield ultimate teleport thing, I will suggest a full kit rework. I want to make him a pusher in terms of wave clear to apply pressure in that regards to force someone to deal with a pushed minion wave and then he ultimates to his team creating a 4v5 scenario. Something I will try to avoid is actual efficient tower pushing and dueling (everyone hates that Jax, Yi, Tryndamere, Nasus split pushing in solo queue). In return Shen will become a greater tank for team fighting, peeling, and of course damage sponging.
Ki Strike (Passive): Static Cooldown: 12/10/8/6/4 seconds [@levels 1/5/9/13/17] Shen's next basic attack or Vorbal Blade deals 4% of his maximum health to and around his target [approx. ~375 units] as bonus magic damage (200% increased damage against minions).
Vorbal Blade (Q): Cooldown: 6 seconds; Cost: 60/55/50/45/40 Energy; Range: 600 units Shen throws a blade at a target enemy to mark the target for 3 seconds and deal 80/120/160/200/240(+60%AP) magic damage. Shen's next basic attack against the marked target will consume the mark to slow the target by 25/35/45/55/65% for 2 seconds and restore 6/7/8/9/10% of Shen's maximum health. If an ally champion's basic attack consumes the mark then they are healed for half the value and the slow duration is only 1 second.
Feint (W): Cooldown: 14/12/10/8/6 seconds; Cost: 50 Energy Shen will feint causing all incoming enemy attacks or abilities to miss Shen for the next 0.75 second.
If Shen uses Feint while an enemy champion is currently taunted then the attacks will still hit Shen, but then 40/45/50/55/60% of the damage is reflected back at the attacker.
Shadow Dash (E): Cooldown: 24/20/16/12/8 seconds; Cost: 60/65/70/75/80 Energy; Range: 650 units Shen dashes in the target direction taunting struck champions for 1.5 seconds and dealing 60/90/120/150/180(+10% Bonus Health) as physical damage to all enemies. Taunted champions deal 40% less damage to Shen.
Every enemy champion taunted restores 30 energy to Shen.
Stand United (R): Cooldown: 200/170/140 seconds; Range: Global Shen channels for 3 seconds to teleport to a target ally champion and while channeling the ally champion gains 80% damage reduction. Upon a successful channel Shen gains 60/70/80% bonus movement speed for 5 seconds when moving towards enemy champions.
Hope you appreciate the rework concept for our beloved ninja tank, Shen! Have a nice day everyone! ~ Stacona
