Omen champion idea

http://leagueoflegends.wikia.com/wiki/File:Omen_Alternatives.jpg I have made a champion idea of Jar'Zod before but i want to do another one of the cancelled champion Omen, i was thinking he could be a jungler assasin with a unique resource type.

passive: Drill Spikes. 4 charges. instead of using mana Omen uses his 4 natural drills sprouting from his back, when hitting an enemy with a drill it sticks in them, killing the enemy drops the drill and being out of combat regenerates drills.

Q: Drill shot - 1 drill - 7/6/5/4/3 Omen shoots a drill to where the mouse is, stopping on the first target hit dealing 50/60/70/80/90 damage and slowing them by 20/30/40/50/60%, if the target dies the drill keeps going and the damage increases by 10 and slow increases by 5%.

W: Artillery/Frontline - no cost - 1s Artillery: Omen switches to ranged, shooting his drills, each right click in artillery is 1 drill cost and has 150/155/160/165/170% more damage but is 50% slower. frontline: Omen switches to melee, chomping and slashing his foes reverting to his 100% damage and 100% attack speed.

E: cowardice - 1 drill - 15/14/13/12/11s - can be cancelled during running Omen normally chooses fight over flight, but not now, Omen runs 100/120/140/160/180% faster and removes all debuffs but takes 2x damage while running. can be cancelled during running.

R: No One Escapes - drills stuck - 120/110/100s All drills get ripped from enemies for 200/300/400 damage and slowing them for 90% and revealing them for 5/6/7 seconds, Drill shot gains more range when enemies are revealed.

again im not good with balancing the abilities but i was thinking of a more chasing down enemies jungler.
