There are actually a few type of KS

1.Accident auto attack supports usually have this problem if they are overattacking or casting spells can't be avoided anyways accident can't be avoided unless you dun want to play the game.

2.Killsecure KS when you are chasing an enemy but unable to reach him your teammates come in and kill him for you it a form of KS but it killsecure.

3.Purposely KS yup seen tons of this cases when a kha zix ( many others champs too) just come and Q away the enemy champion you are aimming while you are the one casting all the spells (i know blah blah that still teamwork) But when your whole team is focusing on the enemy  and that guy is just standing there doing nothing at all suddenly jumped in and take the kill and says that he carried the game cause he got the most kills now that really KS
