There's a certain type of player
That doesn't understand the connection between them dying and the enemy getting kills. It's a weird cognitive dissonance but they conduct themselves as if their deaths are non-kills and have no bearing on the enemy.
If you were to ask one of these people - who has the better KDA? The Jungler who is 3/6/1? Or the support who is 0/0/3? Their response is something to the effect of "You don't even have any kills you fucking newb."
Has anyone had any success in getting through to these people? Any advice is hugely welcome.
