User blog comment:Juper0/Solo'able Baron?/@comment-24087642-20140330075645

You say the risk-reward ratio is pretty high. But the thing is, if the enemy has warded it at all, which they should've in ranked, they'll kill you and baron. Moreover, you usually have to build for soloing baron, which could hurt your game, especially if you fail.

The more the enemy expects it, the more risky it is. It basically might counter the meta and that might be the only reason it's strong. Why punish people for countering the meta?
