So my wife, my friends, and I have been experiencing this problem where they are either leashing or supporting me/ally and when they leave when the enemy is about a quarter life (25-30% at least) to allow the adc or jungler to gain the kill it instead decides to award the kill to the supp/leashing ally instead. This has happened to happened to other players as well not just me and the thing is they also back off from the enemy.
Scryer1 votesDamage over time effects could cause this, in which case it is not a bug, perhaps some more specific instances could help people determine if this is truly a bug, better yet, a video could help.
Varken201 votesI took into consideration of the 'damage over time' effects but none of our champs, maybe save a couple, have that kind of ability. Generally when Her or I use a champ like that we know what to expect.
