No point in jungling in URF but that is how it feels to take drag :D
Also this gif gives me the urge to watch spongebob..haven't seen it in like 4 years
As far as scaling goes fellows, doing 500-1000 true damage to a minion and having 20% spellvamp helps you heal in lane really fast. that and e-snowball will also give you health back. Think of Urf Nunu as an outsustainer. Nunu can clear jungle fine and well, Nunu can duel fine and well, but they cannot outrange at all. Consider the pick for peel and having a good soloist in top or bottom (Malzahar, Ezreal, anyone with a distance poke longer than 600 and can't be hit, or can push hard should work).
basically you want smite so you can dumpster the drake real fast at the moment he spawns then go back to lane your xp will be the same.
or u could not let your top laner 1v2 and feed 5 kills in 5 min. costing the game as you pve.

I HATE NUNURF.
I played a match and he stacked cinderhulk and a ton of HP and he had over 10 million HP (because everything x1000 in URF) we couldn't even tickle him and he melted everyone who looked at him because of gromp buff.
