Nunu (and WIllump) rework concept

Nunu's current kit has one singular purpose; make the enemy team more useless than himself.

In my mind, this is a very unique playstyle that should be preserved. Nunu is a denial based control jungler; he denies you money and XP by stealing your camps, he denies you objectives by eating them, and he denies you lategame relevance by sapping your stats.

I think this should be maintainted; the same way Singed (if he ever gets some semblance of a rework) should remain a "Diversion" champion, and how Urgot (when he gets reworked) should remain as "Bruiser Artillery with an Airdrop" (is there anything more unique than a champion who is basically an M1 Abrams falling out of the sky to kick ass?).

Moving along, to the Yeti. I find his current Q and Ultimate to be great spells. His passive feels a bit odd. His W is completely out of place, and has no synnergy with the rest of his kit. Nunu himself is either built as a pure tank or as AP. His E just feels really boring both to use and play against; click a guy, guy gets slowed. Rinse and repeat. Unless you build AP, it doesn't even deal damage.

Willump and Nunu, the Yeti and Rider

Passive: Heavy Hands 10 second cooldown If available, causes Willump's basic attack to deal (10 per level) (+20% AP) bonus magic damage, knock the target back slightly, and slow their movement speed by 30% for 1 second.

Q: Consume Noted that Willump consumes the target.

W: Heat Sap 15 second cooldown Summons a freezing aura around Willump for 4/6/8/10/12 seconds. Every second spend in the aura slows the movement and attacks of nearby enemies by 10% per second, up to a 30% slow. Willump absorbs heat from each unit he chills, granting him buffs. Tagging a non-champion grants Willump 2% movement speed for the rest of the duration. Tagging a champions grant Willump 5% movement speed, 5% tenacity, and causes him to regenerate 1% his missing health per second, all lasting until the end of the duration. (Stacks fully, but the same unit cannot grant these buffs more than once).

E: Boy of the Frost

(Passive) Nunu can act independently from Willump. If whatever Nunu is riding dies (or he dismounts), Nunu can walk around, untargetable, at 75% movement speed. Nunu cannot perform any actions that are not bound to this spell, and Willump can act at his own full capacity without Nunu (controlling normally). (Note: a separated Nunu will only gain gold and XP for the pair for creeps he kills or champions he helps to kill. WIllump can gain for the pair as normal. Nunu will not gain any extra XP for helping Willump kill something, obviously).

(Active) Has different effects for targeting allied champions/structures, enemy units, the ground, and Willump. None of these cast types share a cooldown. GROUND CAST (unmounted only): Causes Nunu to walk to a target location (a movement command, just E instead of right click) (0 second cooldown). GROUND CAST (mounted only): Causes Nunu to dismount whatever he is riding (1 second cooldown). ALLY CAST: Causes Nunu to jump off of whatever he is riding and mount a target allied champion or structure. (5 second cooldown). WILLUMP CAST (only if not mounted on Willump): Causes Nunu to run towards Willump , wherever he is, at 2500 movement speed and mount him (5 second cooldown). ENEMY CAST (mounted only): Nunu lobs a snowball at a target enemy, dealing 80/120/160/200/240 (+ 80% AP) magic damage and slowing the target by 40/45/50/55/60% for 2 seconds. (70/75/80/85/90 mana, 6 second cooldown). Nunu can only hold 3/3/4/4/5 snowballs at once, and will restore his stock upon mounting WIllump. The range is centered around Nunu, and whatever he is riding. Mounting a Turret grants bonus range.

(I know it's a wall of text) tl;dr Nunu and Willump are not the same unit. Nunu can move on his own, but is only able to walk around, ride people, and throw snowballs (while riding). (Note: If this sounds familiar, it is because it is based on one of Kled's earlier Ultimates, which caused him to ride an enemy and beat the shit out of them. The difference here is that you ply

R: Absolute Zero Noted that Willump casts this.
