Is it really so hard to NOT feed?
Losing is annoying, granted, but there's a difference between losing a fair fight, and the feeling of hopelessness you get when all your team decides to die over 10 times each.
Besides Aram i didn't get over 6 deaths in a while. It's not hard to play safe when behind. Yet i keep encounterring people that go over 10+ deaths in almost everygame, and that keep dying over and over again despite your best attempts to convince them to play safe and build accordingly.
