A Xin Rework

So I noticed that with Xin's kit, he's a little boring and bland. He just AA's everything to death. Here's a rough draft for a rework.

Passive-Courage

As Xin Zhao moves towards enemy champions, he builds stacks of Courage. Courage increases his movement speed up to 15%, and up to 10 additional attack damage for each nearby champion. The movement speed does not stack.

Q-Counter Strike

Passive: For every attack Xin Zhao recieves, he will have a 20% chance to dodge the attack and and counter attack for 50% of the damage he would've taken. This passive can only dodge auto-attacks.

Active: Xin Zhao heightens his combat senses, doubling his counter strike chance and causing him to counter attack for 100% of the damage he would've taken instead of 50% for 3 seconds.

W-Inspire

Xin Zhao inspires his teammates, increasing their movement speed by 30%, and armor and magic resist by 25 for 5 seconds.

E-Battle Rush

Xin Zhao charges in a straight line, dealing physical damage to all enemies hit and slowing them by 30% for 1 second. It also destroys 20% of their current armor and magic resist for 2.5 seconds.

R-Duel

Xin Zhao challenges an enemy champion to a duel, forcing them to fight each other for 7 seconds. Xin Zhao and the enemy champion take 80% reduced damage from all other sources during this time. If Xin Zhao wins the duel, he will temporarily gain 50 attack damage and 30% movement speed for 5 seconds. If the enemy champion wins, they will gain 50 points to their primary damage type (magical or physical) and 30% movement speed for 5 seconds.

Any thoughts?
