At what Elo is significant game knowledge present?
I'm playing around high silver to mid gold level, and for some reason people still don't have the brains to buy an Executioner's against Soraka. Then there's the idiots that shotcall Baron because it's so smart to do Baron with 4 low health members, 2 inhibs down at ally base and everyone else alive. Serious question, but at what elo do people start recognizing that it's not all "flash in 1v5 oh big play$ I carry 0/5" mechanics?
