Classic Thread - Perfect Team Setup(s) and 3 Bans

Interested in getting opinions from the community (especially high ranked players).

Don't take the term 'perfect' too literally because the 'perfect' team depends on the enemy teams picks and bans. I'm talking about the theoretical best team setup(s). Title for attention.

Here is my opinion: (take it with a pinch of salt please)

---

Perfect team:

Solo Top: Tryndamere

AP Mid: Veigar

Jungler: Skarner

Support: Sona

AD Carry: Graves

Bans: Ryze, Caitlyn, Kassadin

---

Tryndamere counters AD with shout. Veigar counters AP. Sona + Graves wins lane. Skarner stronk jungler.

Getting rid of Ryze because he counters Veigar hard, getting rid of Caitlyn to make bot lane easier. Kassadin is annoying. Hope enemy team bans shaco.
