A Cowardly Champion

I saw someone on Reddit recently suggest there be a cowardly champion in addition to all the epic heroes we see for League. Here's my crack at it:

Mink, The Fearful Scientist

Mink is a master of Hextech crafts, as he wanted desperately to be able to use some of the powerful magic he witnessed others use. His inventions don't always work as intended, though.

Passive: Leave me alone! Mink prefers to keep his distance in battle, and has a standard auto range of 550. However, Mink acknowledges he's not very good at keeping his distance, so he has a backup plan. When enemies are within melee range, Mink has an auto range of 175 and equips his spiked gauntlets, dealing bonus physical damage to enemies on hit.

Q: What was that!? Upon thinking he's heard an odd sound, Mink performs the old Duck and Cover, leaping out of the way in a target direction and then rolling a short distance. However, Mink forgot to un-equip his gauntlets and jumps with abnormal force, dealing bonus physical damage to enemies in his path and applying on-hit effects. If Mink collides with an enemy champion, he instead rolls in place upon landing and knocks back that champion a short distance. The initial leap can cross thin terrain.

W: Take this ... ? In an attempt to mimic the art of a mage, Mink throws his custom-made hextech grenade. ... Er, Mink drops his hextech grenade. The explosion shields Mink for a set amount of damage for 2 seconds. Enemies within 200 units of Mink receive the shield amount as magic damage and are blinded for the duration by the residual smoke.

E: It's my turn! Mink decides to take his defense into his own hands by setting up a perimeter and preps a hextech explosive at a target location. The mine doesn't work properly, though, enabling enemies to see it. The mine has 2 HP and explodes within 500 range upon being destroyed by an enemy (meaning only certain champs will be able to safely destroy it). If Mink is within 1,000 units of the mine, he can reactivate this ability to increase the detonation range to 750 units, dealing magic damage to enemies and stunning enemy champions for 1 second. The active explosion deals bonus damage to minions. Only one mine can be placed at a time.

R: That's it, I'm out of here! Mink decides it's time for a tactical retreat and unleashes his ultimate creation: A giant homeward-bound hextech missile. Mink hops aboard the missile and is launched at a high speed toward his own Nexus/Fountain. The ignition of the missile blasts enemies behind him away and they suffer heavy magic damage. Enemy champions in the missile's path are knocked aside and suffer physical damage. Minions within range of either are executed. This attack has global range and Mink is Unstoppable while atop his missile. He will always arrive back in his base.

So what do you guys think? I don't have a Reddit account myself, but it'd be cool if the user who initially suggested this idea would see this on the boards. I think this champ has potential.
