Zion the Inquisitor

Zion is intended to be a bruiser type that has a unique opportunistic kit to fit a variety of situations. Zion utilizes two whips for medium ranged attacks, like Thresh.

Zion was once a religious leader, but after his home was broken into and his family murdered, he found himself stopping at nothing to find the one responsible for his suffering. Zion eventually found the lowly crime syndicate thug, and after hours of torture, and returning the suffering tenfold, he found the answers he needed. Now Zion works his way through the syndicate, searching for the leaders ultimately responsible for his family's deaths. Zion has found himself going to any means necessary to extract information from his victims, driven by the emptiness he feels in his soul. The criminal underworld has become to know him as the Inquisitor.

Passive: Confessions of Sinners Every time Zion damages an enemy champion, he gains a "confession" stack. Confession stacks can be spent for additional effects on his W, E and R.

Q: Purge Active: Prepare to use current confession stacks. Passive: Each confession stack provides Zion with 0.15 AD and 0.15 AP.

W: Punish Zion strikes out with his whips four times in a forward cone, dealing 25/35/45/55/65 + (40% total AD +15% AP) physical damage per strike to all enemies in range. Punish procs on hits on the 1st and 4th strikes. Spending stacks will stun targets for (0.1 sec / 5 stacks) on the 1st and 4th strikes.

E: Penance Zion deals 4/5/6/7/8% of his current health to himself as physical damage. Penance removes all CC on Zion and reduces all incoming damage by 8/10/12/14/16% for 3 seconds. Spending stacks will increase Zion's move speed by (1 MS / 2 stacks) for 5 seconds.

R: Purification Zion roots himself and flings out his whips, rooting the first enemy champion he hits. Zion repeatedly whips the rooted enemy champion for 150/250/350 + (60% bonus AD + 25% AP) physical damage over 3 seconds. Spending stacks will cause the rooted enemy champion to bleed for (1% max health / 20 stacks) over 4 seconds.

Feedback is appreciated. I feel like Q is pretty underwhelming, but I am not sure how else to make it work. The numbers will no doubt need tweaking.
