i already see some problems with nunus new kit

Issue #1: very long, ranged cooldowns. his ranged dps skills are both stuck at an abysmal 14 seconds for their cooldowns which even at max cdr will still be longer than his current base e cooldown at lvl 1.

Issue #2: (this could be mitigated by a moderate minimum damage on w but no stats were provided for that in the tooltip) he lacks significant ranged damage. Sure his w can scale up to some good damage but unless its damage at the length of the roll after he lets it go after starting from activation is on par with his current e then he will lack adequate burst.

Issue #3: Canceling his ult was and will still be too easy, survivability while channeling is an issue a fraction of the time that simply being interrupted is.

Issue #4: He's got no movement abilities aside from an abysmal 10% ms increase that relies on being in melee range to activate.

Issue #5: he doesnt have good enough peel. His e is far too delayed and too short duration to be effective. His w requires him being what looks like animation locked while facing toward enemies which likely mitigates any ability of his to escape by using it.

Issue #6: The cc on e is too short to justify the long cooldown in addition to the abysmal damage.

Solutions: 1+2+6: vastly increase the damage done by e. Allow nunu's part (the snowballs) to be cast while the skill is on cooldown.

3: Half of his ult shield's health should be magic shield instead. Also consider adding grounded based on some conditions in the aoe (perhaps if the enemy is slowed beforehand then they become grounded in the aoe when it activates or after a duration).

5: Allow nunu to throw the biggest snowball ever behind him while vaulting off of it a short distance. This will give him more useful peel.

4: i think it'd be better if perhaps call of the freljord also activated for him while moving towards an enemy that has been slowed by any ally. That would work well to give him a minor bit of mobility, at least while engaging.
