Nunu easy to ballance with one change

So riot doesn't have time todo a compleet rework for Nunu. Than why not fix him with a mini-rework limited to one ability:

#E - Ice Blast ACTIVE: Nunu throws a snowball (linair skillshot) to it's target (hell you can even use the animation for it if your lazy)

• Monster/Minion: Is now like rootcaller (basicly a non agro mark dash), your next basic attack will now also deal bonus damage to the monster
• Champions: Similar to the old snowball but on a higher cooldown. Hitting the snowball will slow the enemy. Their is a new effect added however. Now the next auto attack dealed by a enemy champion will stun the target (ice block animation) briefly.

So why this would help him:

• E now gives the option to use it as a gap closer or as a lockdown tool. You could for example E to a minion to setup a good ult.
• Similar to his counter jungling will go up. But in return he will lose out some of his damage by using this utility. A good tradeoff.
• Offcourse his E will now have longer range what would allow him to catch targets offguard. It provides a lot of zoning since you never known where he's aiming for. Is it one of the carries or is it a minion where he can use to engage on you. With this mindset people will litterly start soaking the snowball for the treat of the engage.

With one less skillshot in his kit and more uses on it wouldn't this be a good tempory fix for ballancing him.
