What kind of criteria your suggestion holds: Reduce inconvenience.
Good day, I'm opening this topic because I've seen players killing themselves when they're almost died by their opponent, so this topic is simple and no need much explanation since I will provide two videos below.
1. in LV when someone is about to die either he uses RPG or uses a grenade to be killed which is very annoying since you waste bullets and grenades and he ends up killing himself. here is a short video of what I'm talking about Show content

2. in LS the same things happen but not like LV one, for example; 2 players are fighting on roofs and 1 is low, that low hp player suicide by falling down to prevent being killed by the other player who wasted bullets. a video Show content

and same thing can be done with molotoves in LS by the way but I don't have any videos for it, later I will provided another video.
what I'm suggesting: so I'm suggesting that if X player damaged Y player and Y player tried to suicide by any way before 15 seconds pass, the kill will still be counted for X player.
