Not Updated For Current Season
As of late I have really been trying to really press the idea of GOOD Team compilations on myself. Maybe not always getting a good team, but trying to find certain character pairings that would work. The Nunu I play usually is an off tank, simply because there are better tanks for the job( Mumu, galio, shen, rammus, etc ). All of which can help You actually get a good ultimate off during a team fight. One of the biggest things for nunu is drawing CC away from your carry/mage. One of the reasons you see all Nunu's carry a banshees veil is because it forces the enemy team to use atleast two skills on you. Somethings its easier said than done.
I like a jungle nunu because its better for a team as a whole two have two characters who are significantly higher than the opposing team. You probably will see this is higher ELO games! Also having 2 smites is a great way to clinch a baron buff, or a dragon kill.
My Jungle Rotation goes as follows:
its pretty much open from there. I personally like ganking at 4 because its always good to get your team some gold, or get an early level 2 shoe. Always be aware of your minimap, because while jungling its your responsibility to know whats happening at all times.
Anyways I dont want to get too indepth with this because I am just assuming you have all played enough to know the basics of the game :) Any questions? Feel free to ask! :)
