Ummm...can we nerf Nocturne?

Currently, Nocturne is a 3 position flex pick.

I mainly have an issue with him in the jungle.

I think his W is pretty unfair.

His W gives him a free spell shield. I don't think this is an issue in and of itself, it's a fine ability on its own. Sivir has it, and I'm cool with it. But Nocturne gets a free 30% AS steroid out of it.

His E gives him some free CC, if he stays within range.

And his passive gives him a free Tiamat (most of the time), along with Bonus Damage and Healing.

Now, my issue is not really with these abilities except for his W. It's his kit in general and how it synergizes.

It is practically impossible to 1 v 1 this champion. He is supposed to power farm till 6. You should have a clear window to beat him. Instead, he often easily wins any jungle 1 v 1 even against "early game" jungle champions. His W gives him a free shield that blocks critical damage/abilities from any enemy and gives him enough AS to easily get more damage in than the enemy jungler. He also has his passive which heals and deals a little extra damage. On top of this he STILL has his W, so he can easily block any incoming spell, auto you, CC you, and you just die. What counterplay is there to this? Well, don't fight him early. Ok, that would make sense-but he's a level 6 power jungler. He's not supposed to be that strong early game. I dont' know why a "late game" champion has access to so much early-I would honestly rather face a good Elise/Lee Sin/Olaf than Nocturne, because at least there is something I can do. I really don't see how this champion is fair in the jungle, he wins any duels too easily, has a great clear, and scales really well especially with ult. Needs a nerf imo; Riot hated Pyke in 3 lanes, so why is Nocturne ok?
