Zilean, The Chronokeeper [REWORK THOUGHTS]
is super underplayed, mostly because of his inability to contribute a heal, shield, or deal damage beyond AA's and his Q. I think he needs a rework.
Passive: Time Flux [Range: 1000] {Ally}
For each 2% of health Zilean is missing, him and allies near him gain 1% movement speed.
Q: Time Bomb [Range: 750] {Ally or Enemy}
Places a time bomb on an ally or enemy. After 3 seconds, the bomb explodes, dealing damage to all enemies in the area.

Sends out a giant clock, damaging all enemies it hits.

E: Time Warp [Range: 600] {Ally or Enemy}

R: Father Time [Range: 2000/2500/3000] {Self}
Zilean becomes the embodiment of time, becoming untargetable for a short time. For the duration, there is an entity that will move at high speeds around Zilean, damaging and slowing all enemies hit. The ability is canceled if the entity leaves the range or it times out. Each enemy can only be hit once each time this spell is cast.

Slow: 20%/30%/40%
Entity's Movement Speed: 500/600/700 (+0.3 AP)
