[2020] Official confirmation of important Ranked change not in patch notes: Kills you get in Ranked after you die will count towards RP! Being flushed after knocking 3 and then your team getting the 4th, will give you all the points :)

Specifically, this is tied to the new team placements calculation. Since we now wait until you leave the match to calculate your performance, we can include details that occur up until that point.

Therefor for example, if you knock an enemy and then yourself die before the enemy player bleeds out there are two possibilities: you leave immediately and before the enemy player actually dies and do not receive credit, or you wait until after the enemy player dies to leave and you DO receive credit.
