A rework idea for Nunu

Before we get this started, I will state I am a mastery 4, almost 5 nunu, so take this from my viewpoint. As you all know, Nunu is somewhat of an oddball champion. He counterjungles, then becomes near useless. He is a support/fighter, but isn't either. I think that to capture the theme of Nunu, we really have to incorporate Nunu himself, instead of Willump, his yeti. My proposed rework, no lore included, is the following. New Passive! (Name undetermined) Every time Nunu an enemy or neutral minion with an ability, he gains 1 snowball. (or another item) Reaching different milestones of snowballs buffs different abilities. Q:Consume: Now can target champions at 30% damage W: Snowbomb (Read ability before this) Increases damage by 50% to minions/monsters, and increases AOE by 100 range. E: Ice Ball: Now slows an additional 20% and marks hit target. Nunu gains 50 movement speed while moving towards marked target. Ultimate:Absolute Zero: Larger radius of casting range, while enemy champions in area of, they have their resistances reduced by 20 each. (Milestones undecided, please recommend numbers in comment section below!)

Q: Consume, Scaling change: Deals 400/550/700/850/1000(+15% AP) true damage to target minion or monster. and healing for 70/115/175/205/250 (+30% AP) Gains a buff depending on minion or monster eaten.

W: complete rework: CDR 12/11/10/9/8 seconds Snowbomb: Nunu tosses a snowball that explodes at target location, dealing 5/7/9/11/13% of enemy's health as magic damage in a 250 range radius. Slows enemies by 20% for 2 seconds.

E: Ice blast Tweak: 16/15/13/11/9 secondsWillump chucks ice at enemy/minion or monster, dealing 75/150/200/275/350(+50% AP) magic damage and stunning them for .25/.5/1/1.25/1.5 seconds, and slowing them by 30% for 1 second after.

Ultimate: Absolute Zero,tweaked: Nunu channels for up to 2.5 seconds,slowing all enemies in area by 40%, and decreasing their attack speed by 20% after channel deals 800/1200/1600 (+150% AP)magic damage.

I'd love to hear how anybody things about this idea for a rework, so please comment! If you are just going to say it sucked at least say why
