The question that we did not get the answer a long time ago.Point of being fed is to collect gold not kills .So u can farm,get assists,play safe.Not need to have a tons of kills so u do not need to take every kill.Here we have many opinions about what is "KS". Something like 1.u do all damage and other player come and simply use 1-2 basic ,spell; 2. someone w8 to enemy champion be low hp and than take kill;
But this is MY OPINION only.There is a lot of players who have different opinion.So i recommend RIOT to create a video about ks(what is ks,can we report someone because he steal kill,how ks affect on teamwork...). If RIOT make that video there will be less flame,troll,afk. Video "TEAMWORK OP" change my behavior in the game.
