I feel the game is very well balanced at this point. Especially since they have so many champs to balance.
Only things that seem slightly out of line are
1.Pantheon early game
2.Soraka might need a look
Other than that everything seems perfectly fine in terms of there being no OP champs.
Kudos to Riot, most balanced game i've seen yet.
There aren't "OP" champs, but there are definetly OP team arrangements.
