User blog comment:Kashicorn/What champions do you think are OP?/@comment-174.66.147.235-20121102002128/@comment-5678913-20121102173042

Just because Sona has the AoE stun doesn't make her OP. She's actually the easiest champion to kill. I do agree that she can do a fair amount of damage early game and if she's built right some good damage mid and late game, but she's not considered OP to most people.
