A better player will be stronger with a better champion, but the fact that you're easily winning your lane with Nunu may simply mean that you're mechanically better then the average player you're getting paired with. Your positioning is well and your opponents are overly afraid of Nunu's snowball.
But watch any high level stream. Add some higher level players to your buddy list and spectate them regularly. Between the beginning of season 3 and today, Nunu was basically never picked for reasons I mentioned earlier. He's not a laner and never has been.
I haven't tried Nunu in a real game yet, but I just tried his jungle run out. My first impression is that the changes make him extremely strong in the jungle. I'm not a gold+, but based on my impression, I imagine he'll see some action in the jungle once more. Between the speed boost he gets from wolves/wraiths and his W, and the extra damage/tankiness he gets from lizards/golems (the consume buffs STACK by the way... that is to say, you can have one of each all at the same time), he has an extraordinarily fast clear time. And with a leash on blue (that you can still smite... so it's as fast as a smite leash with the advantage of saving smite), you can then go in and you have over 1,000 true damage ready to dish out to the red buff (whether yours or enemies) between Consume and Smite. And you'll get there fast because you have your W and the wolf buff.
Nunu jungle is extremely strong and extremely viable now.
He's not weaker overall. He's just weaker in a role he was already weak in and wasn't intended to be in in the first place. Rather than be an under par laner that was an extraordinarily rare pick, he's now going to be a very strong jungler.
The patch didn't confine him to one role. Nunu was intended to be confined to this one role from inception. The previous strength of his W temporarily made him a viable support. The nerf to his W and the changes to his jungle made him weak across the board to the point that it made him seem like he could play in lane.
That's not a testament to how good Nunu is as a laner--it's a testament to how weak Riot had made him as a jungler. And with this patch, Riot has finally fixed Nunu as a jungler as far as I can tell.
