Top lane: a lot of choices. Just the ones that become monsters when farmed. Riven or Nasus come to mind but it could easily be someone else.
Jungler: Skarner, Lee Sin, Shyvana. I want tanky bruisers that are going to have no reservations about going balls deep into the enemy team. Skarner is exceptional because of his initiation and constant disruption due to aoe slow. That and he's incredibly tanky vs AD and his damage output is massive.
Shyvana has no cc but makes up for it by being a ****ing dragon, being in their face and really screwing up their positioning just by being in their face. Lee has great ganks and a lot of counter-jungling opportunities. Aoe slow + attack speed debuff is great in teamfights and has some of the same qualities as Skarner but just not constant.
Ap mid: Cass, Kennen, Karthus High consistent damage and very strong ults, combined with great crowd control. What's not to love?
Support: Janna If your ad carry doesn't play full ****** then you don't need sustain. Her constant disruption allows your bruisers to stick to their targets and allows you to peel entire teams off.
Bot ad: any of the top ad carries. I would pick sivir but that's just me.
Janna, Skarner, and Kennen would make any initiation on your team backfire in your enemy's faces. They just let your solo top and ad bot do their jobs and tear into the enemy without much retaliation. Throw into that mix some disruption from Riven or a Nasus... or Shen, or Renek, etc.. all this while your ad carry is safe behind bruisers and multiple peel options with +50dmg from Janna's shield.
ya now I wanna try this.
