What kind of advice is "don't feed"?
Because I sure would like to improve and this kind of shit statement doesn't help in that regard.
"Don't overextend" is advice
"Freeze and position to be able to move back to tower" is advice
"Don't engage without X Y or Z condition" is advice
"Call for ganks when the enemy is extended" is advice
"don't feed" is an overly vague statement that seems to be spouted exclusively by bronzes and unranked toward other bronzes and unranked players in lieu of acknowledging their own mistakes in play.
