User blog comment:RoznosicielCiast/Darius is NOT the most powerful champion in League. Which champs are stronger than him in your opinion?/@comment-37.35.25.30-20130122200809

Chogath might be slightly op due its versatility. Garen... not so much. There is a reason garen is not played. Its him falling of after 10min.

Truth is that more than champions inbalance, the amount of you played against certain champion does a big difference. It doesnt matter in high elo tho, because player levels are too near each other due lack of players.
