Can Nunu has some little rework

Hello, I would like to keep this short... After Rework of runes has not been successful , Since Stoneborn pact is not available His ult is the easiest dodge-able with high Mobility champs or any champ with Dash/flash/jump , and gets Cc hard to prevent him from casting his ult My suggestion would be to only rework his W into something similar to 's W , Willumps Drops the temperature around him using his Yeti Blood causing nearby Units to take 10 / 15 / 20 / 25 / 30 ( 0.2-1.5 % of his Max hp ) And Willump Gains bonus Movement Speed . If visionary is active it grants Closest Allied champion 35% Attackspeed and 10% Movement speed to all allied champs within Radius . i am sure This would help Nunu Significantly and Nunu wouldnt require To deal damage he could straightly go for Tankiness even if he wont be able to cast his ult he can do damage without Building Magic Would be strange to have Big OL' Yeti willump build only Magic and act like Caster
