Tryndamere rework idea

Passive: Builds fury from attacking units(besides structures) and his fury gain is increased when below 50% hp. Each point of fury makes him swing his sword harder, increasing the damage of his autos by a bit. Once he reaches half his fury bar he uses his current crit animation. Any crit chance Tryndamere buys merely increases the damage of his autos(sort of like Ashe).

Q: A heal that heals more based on his fury. He also passively gains AD the lower health he has.

W: On activation Tryndamere gains a buff that increases his movespeed when chasing fleeing enemies that he has damaged or been damaged by in the past 5ish seconds.

E: Dashes in target direction while spinning, stopping at the first large monster, scuttle, or enemy champion dealing damage on the way. The enemy hit(excluding minions and small monsters) is slowed for a large amount over 1ish seconds.

R: Gains some fury and is unable to be killed while he has fury. After his health reaches 1 his fury starts to take the hit instead based on his AD. When his fury reaches 0 or the timer of this ult is over he can die.
