Feeders get sensitive after getting called out.
We all have feeders in one of those games and whenever you point out to them that they are feeding automatically they go on the defensive. Some just blame you for their mistakes after being called out. I mean if you are just pointing out they are feeding and should play safe shouldn't even be consider taken as offense.
as yasuo
. I was able to make him back, then what does our genius Lee sin do while im backing, try to 1 v 1 him when rengar is level 4 and lee sin is still level 2 and was executed at the jg. Main problem for yasuo with a champ like rengar early game is going to be farming top lane since rengar will pretty much be able to attack and junk 75% of ur health away anytime u try to cs anything thats not under ur tower.
