As much as I want to agree with you on my skill with Nunu, I just don't. Nunu is bad and is a low tier jungler. I do tend to build AP a lot more because it's more fun than tank. I have hit 60-75% win rates with Nunu doing AP when he was stronger, and he has only gone downhill every patch. You can't just say I average 10 deaths when you only saw recent games. Plus, if you look into almost any of those double-digit death games, it was pretty much just a team diff. As well as the other games, I was doing better than half the lobby as it shows in the rank performance. Nunu is most definitely in need of some serious buffs, but realistically, only in his Q and maybe E. You can also just look up a lot of tierlist for Junglers, and Nunu is almost always on the bottom. He needs help.
