When your teammate tilts you
"stop feeding"... when you're against a champ that chases you non stop. Ok, not joining team fights because I don't wanna feed.
"play safe"... when your opponent turret dives you constantly. Ok, stay away from your lane opponent.
"you're pushing too deep"... when you're as far as blue buff with inner turret still up. Ok, no more defending turrets.
Outcome? Loss a winning game because jungler decides to make these comments and I followed and he goes "report" when our ADC is 1/11 while I'm 3/7. He didn't gank my lane once and at 16 min when I was 1/3, he said "just wait for me".
Moral of this story? STOP MAKING UNNECESSARY COMMENTS TO TILT YOUR TEAMMATES. IT'S UNPRODUCTIVE.
