My thoughts on Skarner

RIOT seems like they just aren't sure what they want Skarner to be. They aren't sure how his play should feel and they always seem to think his dmg is too high. Using their current direction and what not, I wonder if this wouldnt be closer to what they want:

passive: crystal spires changes: MS Bonus: 50 (down from 100) Mana Regen: 1% per second (down from 3)

Q: Crystal Slash changes: Damage: 32 / 34 / 36 / 38 / 40% AD NEW: hitting opponents with Crystal Slash grants Skarner a stack of crystal energy (max 3 stacks). While within range of a spire that he controls Skarner passively gains 1 stack per second. Stacks all fall off after 3 seconds if not refreshed. Each stack grants Skarner 2 / 3 / 4 / 5 / 6% increased movement speed and 3 / 4 / 5 / 6 / 7 bonus armor and magic resist.

W: Crystalline Exoskeleton changes: Shield value down 2% at all ranks. (10 / 11 / 12 / 13 / 14% max HP) AP ratio down to 50%.

E: Fracture changes: Base damage up at low rank down at high rank. Ratio up. Damage: 60 / 70 / 80 / 90 / 100 (+100%AP) Slow: 50 / 55 / 60 / 65 / 70% for 2.5 seconds. Bonus Damage: Removed. NEW: When Skarner AA's a target marked with Crystal Venom he heals for 6 / 7 / 8 / 9 / 10% missing health (+1% per 50 AP). Heal increased by 50% vs monsters if within range of a spire that he controls. No longer reduces cooldown with stun procs. Cooldown is 14/13/12/11/10

R: Impale No changes.

Thoughts: Skarner is a sustained damage fighter. Taking a bunch of his damage and replacing it with sustain pushes him more toward the juggernaut identity that I think riot is aiming for. Shifting some of his power out of his passive back to Q makes players feel like he can play more than just jungle. His passive will still make jungle his best spot and he will be powerful within his zones making him great at objective control. Thoughts on this?
