I have to say Teemo/Maokia. Teemo can rock a lane with an AD in it pretty well and trap the lane discouraging ganks. Where as Moakia has near infinite sustain once you get mana regen because of his passive if you are against casters that don,t use mana.

1. Nasus (derp)
2. Jax
3. Gangplank I think, even if he is not popular nowadays, his late game is pretty beast.

The second you pick nasus in a ranked game is the second you lose the game, he's only good for solo que. In ranked/draft you'll get counter picked and smashed for 20 minutes straight until you surrender. He's melee, no gap closer, no proper ranged harass, mana hungry, and not inherently tanky.

Nasus and Kayle are the first 2 to come to mind.

nasus is by far the worst champ in my opinion. He is so heavily dependant on farm, and because of that is almost never in early game fights. Leaving it 4v5 which most often ends in someone on the enemy team just as fed as him if not more.

Late game? Kennen, vladimir, nasus (but he's nonviable unless you're laning against like a cho). Urgot works too, but urgots just broken so he goes any lane he pleases :3

Must be Tryndamere

I had thought that Yorick had a really weak late-game, for some reason. Not sure where I read that.

... nasus, irelia, and maybe a good jayce
