Nunu Update
For the love of God, please, pretty please do a Nunu remake. Why does he only get one offensive spell while his ult is stopped by literally everything. There are far too many knock ups in the game to have an ult like that. His w works well the ADC, but half the time the mobility still doesn't cut it or you when you gank they already see you. Not to mention his passive makes him such a big target for poke if you play him in lane and 5 is a HUGE number for a slow hitting Nunu without wanting to use your w.
Nunu needs to have some huge changes and I have the suggested Idea. Slushed- His passive would be that with each champion he hits he reduces their MR and Armor by 3%(times the number of hits he has on that champ which can go up to 4). Also the champ is marked with an icon to notify the ally team of the passive stacks Nunu Smash- His Q should be a smash onto the ground that hits in a line and if it reaches a champion it should knock them up. Like a Braum ult but only affecting the first enemy it comes across. Cold Burn- His W should be an enhancer specifically for him that gives him straight AP based damage on hit for the next three hits. Also these hits are not a typical Nunu thrust but a swing so it pushes the enemies back with each hit. Ice Blast- His E should be the classic snowball. Snow Day Flurry- His R should be Nunu should be Nunu in a rage throwing snowballs for a certain duration i'm thinking 4 seconds in any direction BUT he has to stay mobile. I mean a flurry of snowballs like Lucian with his ult but this substitutes mobility for angle.
His game play will be a lot more reliant on AP to scale off of but he could still be an amazing tank if need be. Also he would have a fascinating combo. Early game he could flash behind enemy push them into turret with Cold Burn then Nunu Smash whilst in your turret.
