User blog comment:Kashicorn/What champions do you think are OP?/@comment-89.142.216.73-20121106193918

IMO, not a single champ is op hence they have multiple counters, if a champ becomes op (most likely within release) it gets nerfed next patch or a patch after it.

PS: if you think a champ is op, think about how fed the player is, items are what make champs "OP".

I've also seen people bitching on things like "HEIMER OP!" even tho he had multiple nerfs, as every champ, he gets damage by buying items.
