Nunu idea (It involves snowballs)

Soooooo i'll just throw here a crazy idea that could be interesting for a reworked Nunu!

Snowball:

-First cast: Nunu creates a snowball in front of him. He can have multiple snowballs at once, and they don't despawn, but if Nunu isn't around, they can be stomped and destroyed.

-Second cast: If Nunu recasts this ability close to one of his created snowball, he pushes it in a straight line in target direction, and the snowball rolls until it collides with a champion or terrain.

-Snowballing: The snowball initially does 50/80/110/140/170 (+40%AP) (+6/7/8/9/10%total HP) and slows enemies hit for 40% for 2 seconds, but Willump can push the snowball around by walking into it, slowing his own movement speed by half that amount (20%) while pushing. The snowball grows in size and strength as it is being rolled, and gains benefits after being rolled a set distance: 1000range: Total damage and size increase = 100%, enemy slow = 80%, self-slow while pushing = 40%. 2000range: Total damage and size increase = 200%, now stuns enemies hit for 1 second before applying a 80% slow for 2 sec, Self-slow = 60%. The snowball doesn't get destroyed upon champion collision anymore. 3000range: Total damage and size increase = 300%, Stuns for 2sec + slow, self-slow = 80%. The snowball now becomes impassable terrain for enemies, but becomes targettable, and has 50% of Nunu's health and half his armor and MR. For every additionnal 1000range: Total damage and size increase = +100%, self-slow = +20% (capped at 90%), snowball health = +50% Nunu's health

-Note: There would be a visual indicator for the progress for each bonus increment. Size, damage and slow scales linearly as it grows, but other bonuses only take effect after reaching certain increments. After Nunu shoves the snowball, the snowball still gathers in strength as it travels.

-Bonus: At lvl 6/11/16, Nunu can ignore the first 10/20/30% of the self-applied slow when pushing the snowball.

Inspiration: By developping the idea of Nunu throwing snowballs, i used the fantasy of a snowball growing as it rolls down a hill. This ability could satisfy both tanky and AP Nunu with it's scaling. It is also a combination of his ult and his E, you try to charge the ability as much as you can and hope to unleash a powerful blast. Being able to lay multiple snowballs around could help Nunu with his jungle control, either by blocking paths, or even by baiting enemies into a fully grown snowball, much like how he would try to bait enemies into his ult. He could also try to snipe people by rolling a huge snowball accross a lane, as it grows in size and strength.
